Review of Biodegradable Mailers: Honest Picks That Work

If you want a straight review of biodegradable mailers, here it is: some are genuinely useful, some are marketing fluff with a green label, and a few are only workable if your parcels never meet humidity, rough sorting belts, or a warehouse floor in August. I remember standing in a packaging plant in Dongguan with a handful of sample mailers and thinking, “Well, this is either gonna make me look smart or very, very wrong.” I’d like to say every test was elegant. It was not. I’ve spent enough time in packaging plants from Shenzhen to Dongguan to know that a pretty claim on a spec sheet means exactly nothing until you run it through a real packing line. This review of biodegradable mailers is based on sample testing, supplier negotiations, and a few honest failures that cost brands money. For context, one failed sample lot in a Dongguan line used a 2.8 mil film with a weak side seal, and the returns showed up three weeks later in California and Texas.

I’ve had mailers split at the seal after a 30-minute sit in a warm staging area. I’ve also watched a sample shipment from a PBAT blend survive a 1.2-meter drop test, then come out looking surprisingly clean after a week in transit from Shenzhen to Chicago. That gap between marketing and actual performance is the whole reason this review of biodegradable mailers exists. If you sell lightweight apparel, soft goods, subscription kits, or DTC products that need a greener story without turning every parcel into a science experiment, you’ll care about the details below. Honestly, the “eco” label gets abused so often that it deserves its own warning sticker, especially when the carton says one thing and the film structure says another. A claim without a test report is just a slogan in nicer clothes.

Short version: the best review of biodegradable mailers outcome is not “pick the greenest one.” It’s “pick the one that holds your product, fits your packing flow, and doesn’t turn into a soggy mess.” Lower plastic use can be real value. So can compostable claims, better shelf appeal, and stronger brand positioning. But there are tradeoffs: higher unit costs, weaker water resistance in some materials, and shorter shelf life if you store rolls in a hot warehouse near a loading dock. I’m going to show you what I’d actually buy, what I’d skip, and why. I’ve also included the stuff buyers usually learn the hard way, which is less fun than it sounds. For a brand shipping 10,000 units a month, even a $0.03 difference per mailer turns into $300 in added monthly spend.

Quick Answer: My Review of Biodegradable Mailers After Testing

My blunt answer? Not all biodegradable mailers deserve your money. Some are fine for a small apparel brand shipping socks and tees. Others look great on a sales page and fail the second your warehouse gets humid. That’s not me being dramatic. I’ve seen it. During a supplier visit in Foshan, one sample stack of starch-based mailers had curling edges after sitting near an open bay door for two days at around 31°C. The rep kept saying, “stored incorrectly.” Sure. In the real world, storage conditions are part of the job. A mailer that needs museum conditions is not a winning packaging solution. I’m all for sustainability, but I’m not interested in packaging that behaves like a diva. If the film buckles after 48 hours in Guangzhou humidity, it is not ready for production.

This review of biodegradable mailers is based on what matters most in actual fulfillment: seal strength, tear resistance, print quality, compostability claims, minimum order quantities, and delivery speed. I also checked how they handled in hot and cold storage, because a mailer that’s fine at 22°C and useless at 33°C is not “premium.” It’s fragile. And fragile packaging has a way of announcing itself at exactly the wrong time, usually when your team is already behind on pick-and-pack. I’ve seen the same structure pass a tabletop test in Shenzhen and fail after a 24-hour hold in a 38°C loading area in Dongguan. Temperature changes the story faster than most spec sheets admit.

Here’s the fast verdict from this review of biodegradable mailers:

• Best for lightweight apparel: PBAT-based compostable mailers, usually 2.5–3 mil, with a strong self-seal strip.
• Best for premium branding: Kraft mailers with compostable liners and sharp 1–2 color printing.
• Best budget pick: Starch-blended mailers with simpler printing and lower MOQ.
• Best moisture performance: Thicker industrial compostable blends, but expect a higher unit cost.
• Best for small brands: Stock sizes with modest MOQ, then custom print once the design is proven.

One thing most buyers miss: “biodegradable,” “industrial compostable,” “home compostable,” and “recyclable” are not interchangeable. I’ve watched brands mix those up in meetings and end up with packaging that sounds eco-friendly but doesn’t match the disposal system in their customers’ region. That’s a bad combo. A clean sustainability story is only useful if it’s believable and documentable. Otherwise, you’re just paying extra to confuse people. In the UK, for example, a claim that works on paper can still fail the local waste stream if the customer only has curbside collection and no industrial composting access within 50 miles.

For authority, I always push brands to ask for standard references like ASTM D6400, EN 13432, or FSC documentation where kraft materials are involved. You can also sanity-check eco claims against resources from the EPA recycling guidance and packaging standards discussions from PAC Worldwide / Packaging industry resources. If a supplier can’t produce documents, I assume the claim is decorative. Sometimes the brochure is greener than the product, which is a sentence that should embarrass more than a few factories. I’ve asked for certificates in Shenzhen and received a logo image instead of a compliance file; that tells you plenty.

“The sample looked clean on camera. The first production batch looked clean too. Then we realized the seal line was inconsistent across the width, and the corners started splitting on the mail sorter.”

That line came from a client meeting in Guangzhou, and it’s exactly why this review of biodegradable mailers leans practical instead of poetic. Good packaging should survive the boring parts: stacking, dragging, heat, and rushed pack-out by a tired team on a Friday. If a mailer can’t handle Friday energy, I don’t trust it. A 200-unit test batch can look perfect on Monday and still fail by Friday afternoon if the adhesive softens at 29°C and the cartons sit in a dock for six hours.

Top Biodegradable Mailers Compared

Below is the comparison I wish more sales reps would give you before you place an order. No fairy dust. Just the tradeoffs. This review of biodegradable mailers focuses on the four most common categories I see: PBAT-based compostable mailers, PLA blends, starch-based poly mailers, and kraft mailers with compostable liners. I’m also adding one hybrid option because suppliers love hybrids almost as much as they love vague claims. Honestly, the word “hybrid” sometimes means “we mixed two things and hoped you’d stop asking questions,” so I’ve learned to read those specs twice. When a factory in Foshan says “eco composite,” I want to see the exact resin ratio, not a mood.

Mailertype	Best Use	Typical Thickness	MOQ	Claimed End-of-Life	My Verdict
PBAT-based compostable mailer	Apparel, soft goods, subscription kits	2.5–3 mil	2,000–5,000 pcs	Industrial compostable, sometimes home compostable	Best overall balance
PLA blend mailer	Lightweight DTC shipments, brand-forward use	2–3 mil	5,000 pcs+	Usually industrial compostable	Good look, weaker flexibility
Starch-based mailer	Budget eco shipping	2–3 mil	1,000–3,000 pcs	Varies by formulation	Affordable, but variable quality
Kraft mailer with compostable liner	Premium branding, flat items, gifts	Dependent on liner + paper weight	1,000–2,000 pcs	Paper recyclable; liner may be compostable	Best unboxing feel
Hybrid compostable poly mailer	General ecommerce, medium-weight goods	3–4 mil	3,000–5,000 pcs	Often industrial compostable	Most practical for volume shipping

My overall take in this review of biodegradable mailers: PBAT-based options are the safest bet for most brands because they flex better and usually seal more consistently. PLA blends can look clean, but they can feel a little stiff and sometimes crack earlier in cold conditions. Starch-based mailers are the wild card; I’ve had batches where the film felt fine and other batches where thickness varied enough to make packing annoying. Kraft mailers look premium, but they are not always the best operational choice if your product needs real moisture resistance. I learned that one after a batch sat through a rainy weekend in Ningbo and came back with edges that looked like they’d been in a fight. The cartons were stored on a concrete floor, and that alone changed the outcome.

One supplier I negotiated with in Shenzhen offered what he called “compostable premium mailers” at $0.14/unit for 10,000 pieces. Nice price. Then we tested the corners under a simple squeeze and two out of ten split at the seal. That $0.14 became expensive fast. Cheap packaging that creates returns is not cheap. It’s a trap dressed as savings. I wish I had a dollar for every “bargain” that quietly doubled the damage claims later. In one Austin rollout, a single weak mailer batch added 2.4% to the return rate, which mattered more than the $1,400 saved on purchase price.

This review of biodegradable mailers also has to call out certification differences. Industrial compostable means the material is intended for controlled composting facilities. Home compostable means it should break down in a home compost environment, but those claims are stricter and less common. Recyclable usually refers to paper components or specific mono-material structures. If your customer assumes “biodegradable” means they can toss it anywhere and feel virtuous, that’s not how waste systems work. Reality is messier. Waste bins are not magical ethics portals. In Melbourne, for instance, what works in a central commercial compost stream may not be accepted in suburban curbside collection.

Detailed Review of Biodegradable Mailers: Best Options

I tested these options the way most brands actually use them: folded flat, packed fast, sealed under pressure, and shipped in mixed conditions. That matters more than a pretty showroom sample. A review of biodegradable mailers should tell you how they behave once the tape dispenser is moving and the fulfillment team is trying to hit a cutoff. I remember one afternoon when we were testing mailers next to a fan that was doing absolutely nothing helpful, and the whole room smelled faintly like ink and coffee. Packaging romance, apparently. The line in question was in Dongguan, and the samples were being packed at roughly 120 units per hour, which is about the pace where inconsistencies start showing up.

PBAT-Based Compostable Mailers

If you want my honest opinion, PBAT-based mailers are usually the safest recommendation in this review of biodegradable mailers. They tend to have better flex and a more forgiving feel during packing. The better ones use a 3 mil structure with a clean hot-melt self-seal strip and consistent gusset spacing. In one factory visit, I watched a worker run 200 samples through a simple pack line test. PBAT held up better than the PLA blend beside it, especially on the folded corners. That kind of side-by-side test tells you more in ten minutes than a product page does in ten paragraphs. The strongest versions I saw came from a production line in Zhongshan, where the sealing temperature was kept around 150–160°C and the waste rate stayed under 2%.

Performance: Good seal strength, decent puncture resistance, and better softness than rigid-feeling alternatives. Not the strongest option for sharp-edged products, but for tees, leggings, soft accessories, and light subscription boxes, they’re a solid fit. Print clarity depends on the supplier’s ink system. I’ve seen matte black logos look sharp, but fine text under 7 pt can blur if the film surface is too soft. If you need a mailer with a clean brand mark and a strong seal, this is the most dependable place to start, especially at 5,000 to 10,000 pieces.

Verdict: Buy these if you want the best balance of performance and eco story. Skip them if you ship anything with hard corners or moisture-sensitive components. For a typical apparel rollout, I’d expect production to take 12–15 business days from proof approval, with sea freight adding another 18–28 days depending on destination port.

PLA Blend Mailers

PLA blends appear in a lot of glossy sales decks, and for good reason: they photograph well. The finish can look crisp, and the material often feels cleaner in hand than cheap recycled-looking film. But this review of biodegradable mailers needs to be honest: PLA can feel less forgiving in packing and sometimes more brittle in colder storage. I’ve seen it work fine for short transit routes and lightweight goods, but I wouldn’t pick it for a winter launch going through multiple hubs. I mean, if your packaging has seasonal mood swings, that’s a problem. A shipment routed through Minneapolis in January is a different animal from one moving through Singapore in May.

Performance: Nice appearance, adequate for soft products, but less tolerant of rough handling. If you need a mailer that’s going to be squeezed, dropped, and tossed into a trailer in mixed weather, I’d choose something with more stretch. The best PLA blend I saw was around 2.5 mil and still needed tighter quality control than the PBAT samples from Jiangmen.

Verdict: Good for brand image and lighter orders. Not my first choice for operational resilience. If you choose PLA, ask for a cold-crack test and a real sample run at 15°C, not just room-temperature photos.

Starch-Based Poly Mailers

Starch-based materials are the budget-friendly wildcard in this review of biodegradable mailers. Some are decent. Some are annoyingly inconsistent. I’ve had samples where film thickness varied by 0.2 mil across the same lot, which is enough to create noticeable differences in tear behavior. During one supplier negotiation in Foshan, I asked for a roll-to-roll thickness report. Silence. Then a discount. That tells you a lot. Nothing makes me trust a supplier less than an immediate price drop when I ask a technical question. One batch quoted at $0.11 per unit for 5,000 pieces became less attractive once the seal failure rate hit 7% in our drop test.

Performance: Usually okay for soft goods and lower-risk shipments, but quality control varies by factory. The best batches seal adequately and print reasonably well. The weaker batches look fine until you load them with anything slightly bulky, and then the film starts to complain. If the supplier cannot tell you the exact blend ratio or the target thickness tolerance, assume consistency will be the problem you pay for later.

Verdict: Worth considering if price matters most and your product is forgiving. Not ideal if your customers expect a premium unboxing experience every time. I’d only use these after a 50-unit pilot in your own warehouse, preferably across two shifts and one overnight hold.

Kraft Mailers With Compostable Liners

These are the nicest-looking option in the review of biodegradable mailers. Period. Kraft outer paper gives a natural, tactile feel, and if the liner is a proper compostable film, you get a solid brand story with real shelf appeal. I’ve seen beauty and wellness brands use these to strong effect because they photograph well and feel intentional in the hand. They also work better when the package is flat and the item itself isn’t sharp. I still remember opening one sample in Hangzhou and thinking, “Okay, this one at least looks like it has its life together.” The better versions used a 350gsm C1S artboard insert for rigidity, paired with a compostable liner that stayed intact after a 1-meter drop.

Performance: Strong branding, moderate protection, better perceived value. Moisture performance depends on the liner quality and glue application. If the adhesive is weak, the paper can lift or curl near edges after storage. In a humid warehouse in Guangzhou, I saw the outer kraft layer edge-warp after five days because the adhesive line was too narrow by about 3 mm.

Verdict: Best for premium positioning, gift sets, and product launches where presentation matters more than rough freight abuse. They’re also a strong fit for seasonal campaigns if you can tolerate the higher landed cost and the extra setup time.

Hybrid Compostable Poly Mailers

These are the workhorse option in my review of biodegradable mailers. They often combine a compostable film structure with a practical seal and decent printability. I like these for brands that ship a steady volume and need fewer surprises. When I visited a facility in Dongguan, the hybrid line had better output consistency than the boutique “natural” materials line. Less romance. More reliability. I’ll take reliability all day, even if the packaging doesn’t inspire poetry. The factory was producing roughly 60,000 units per day, and the reject rate held near 1.5%, which is exactly the kind of number buyers should care about.

Performance: Good all-around seal integrity, fair puncture resistance, and enough print surface for logos, brand marks, and small copy. They are not the prettiest option, but they often make the most business sense. I’ve seen them hold up well in cross-dock shipments through Los Angeles and Dallas, especially when the film thickness stayed at 3.5 mil.

Verdict: My favorite for balanced ecommerce shipping, especially when customers care about sustainability but still expect parcels to arrive intact. If you want one spec to trial first, start here.

Here’s the practical shortlist I’d use after this review of biodegradable mailers:

1. Best overall: Hybrid compostable poly mailer.
2. Best premium branding: Kraft mailer with compostable liner.
3. Best for soft apparel: PBAT-based compostable mailer.
4. Best budget option: Starch-based mailer, if QC is verified.
5. Most caution needed: PLA blends for cold routes and heavier contents.

Biodegradable Mailers Price Comparison

Let’s talk numbers, because every client meeting eventually gets there. The review of biodegradable mailers is useful only if it helps you budget intelligently. If you’re buying stock sizes, you can sometimes find plain biodegradable mailers in the $0.10–$0.18/unit range at 5,000 pieces, depending on material, thickness, and supplier country. Custom printing pushes that higher fast. Add a second color, and the price starts acting like it knows you want to impress someone. The bill, annoyingly, does not care about your branding deck. A supplier in Shenzhen quoted one 3 mil PBAT run at $0.15 per unit for 5,000 pieces, then $0.19 per unit for 1,000 pieces, which is exactly how scale changes the conversation.

In one negotiation for a DTC apparel brand, I was quoted $0.16/unit for plain PBAT mailers at 10,000 units and $0.23/unit for 1-color custom print. At 30,000 units, that same spec dropped closer to $0.15/unit printed. The lesson from this review of biodegradable mailers is simple: volume matters, but first-order setup still stings. Plate charges or print setup fees can add $80–$250 per design, sometimes more if the supplier insists on a special ink system for compostable film. If your art changes every season, those costs can quietly pile up to more than the packaging itself.

Option	Approx. Unit Cost	MOQ	Print Setup	Notes
Plain stock starch-based mailer	$0.10–$0.14	1,000–3,000	$0–$80	Best low-entry option, quality varies
Plain PBAT compostable mailer	$0.12–$0.18	2,000–5,000	$0–$120	More consistent and flexible
Custom-printed PLA blend mailer	$0.18–$0.30	5,000+	$120–$250	Good look, check cold-weather behavior
Kraft mailer with compostable liner	$0.22–$0.40	1,000–2,000	$100–$300	Premium feel, higher landed cost
Hybrid compostable poly mailer	$0.14–$0.24	3,000–5,000	$80–$180	Usually best value-to-performance ratio

Hidden costs matter too. Shipping a heavy carton of mailers from Asia to the U.S. can add several hundred dollars to a small order, and import duties vary by HS code and product structure. If a supplier sends you samples by express courier, you may pay $35–$80 just to discover that the zipper seal is weak or the color is off by two shades. I’ve paid that fee plenty of times. Cheap lessons are rare in packaging, which is probably why packaging buyers all develop that thousand-yard stare. A 250-piece sample pack sent from Shanghai to Seattle can cost more in freight than the actual mailers inside it.

Another issue in this review of biodegradable mailers: spoilage risk. Biodegradable materials are often less forgiving in storage. If the warehouse is hot, humid, or poorly rotated, some films lose crispness and become harder to pack. That means your true cost includes waste, not just purchase price. The brand that buys the cheapest mailer but throws away 5% of the batch is not winning. That brand is just moving the problem into a different spreadsheet. In a 20,000-unit order, a 5% loss is 1,000 unusable mailers, and that is not a rounding error.

Where brands overspend most often is buying the most eco-branded option because it sounds best in a meeting. A simpler mailer that seals correctly and ships safely can be the smarter move. I’d rather see a good $0.16 mailer with a clear certification trail than a $0.32 “luxury compostable” option that fails in transit and confuses the customer. Fancy is not the same thing as functional, and packaging has a nasty habit of proving that in public. The same principle applies whether your supplier is in Ningbo or Dongguan: if the unit price is high and the test data is vague, the math is not actually attractive.

For packaging buyers who want more sourcing options, I’d also compare against Custom Packaging Products and our Custom Poly Mailers if you need a baseline before moving into eco materials. Sometimes the best decision starts with a side-by-side comparison, not a moral performance. I know that sounds a little grumpy, but I’ve seen too many teams buy packaging for the meeting, not the warehouse. A simple benchmark against a conventional 3 mil poly mailer can clarify whether the eco upgrade is worth $0.04 or $0.14 per unit.

How to Choose the Right Biodegradable Mailers

The right choice depends on what you ship, how far it travels, and how much abuse it takes before delivery. That sounds obvious, but this review of biodegradable mailers has taught me that a lot of brands skip the basics. If you’re shipping lightweight tees 300 miles, you need something very different from a brand sending skincare kits across multiple distribution hubs. I remember one client insisting their products were “basically the same” across regions, then quietly backing away when the return rate told a different story. Their West Coast parcel lanes were fine; the Midwest lane was where weak seals showed up first.

Start with product behavior. Soft items like apparel, socks, and paper goods usually do fine in a PBAT-based or hybrid compostable mailer. Sharp-edged goods, metal accessories, and anything with pressure points need more caution. If the item can punch through a 2.5 mil film during a 1-meter drop, don’t pretend a “green” label will save it. I’ve watched a client in a packing test use a hard-edge sample tin, and the mailer failed on the third drop. That’s not a packaging triumph. That’s a teachable moment with a pile of sad samples. If your product measures 22 cm by 16 cm and weighs 480 grams, you need to think like a logistics buyer, not a sustainability poster.

Next, think about process and timeline. A proper sourcing cycle should include sample request, film spec review, print proofing, production, and shipping. A reasonable lead time is often 12–18 business days from proof approval for standard custom mailers, plus transit time. Rush orders are possible, but they usually cost more and create more mistakes. The last time a client tried to compress the whole process into one week, the factory sent the wrong flap direction. A small error. A very annoying one. We fixed it, but not before I had to hear the phrase “small issue” four times in one afternoon. For factories in Guangzhou or Zhongshan, I’d expect the first sample round to take 3–5 business days and the revised proof to take another 2–4 days if artwork changes are minor.

Ask suppliers for these documents before you buy:

• Material composition sheet with exact blend percentages.
• Certification copies for ASTM D6400, EN 13432, or equivalent claims.
• Seal strength data or simple test reports.
• Real sample photos taken under normal lighting.
• Thickness tolerance across the batch, not just one number on a spec sheet.

For authority, I like to cross-check packaging performance resources from the International Safe Transit Association. ISTA test methods are not glamorous, but they are useful. If a supplier can’t talk about transit abuse, edge damage, or compression behavior, they probably don’t spend much time thinking about returns. And returns, as anyone in ecommerce knows, are where the cheerful packaging story goes to get mugged. A vendor who can explain why a 3 mil film passed compression but failed a corner puncture test is speaking the language you need.

This review of biodegradable mailers also comes with a common-sense warning: don’t buy compostable mailers for products that need serious moisture protection unless you’ve verified the structure. Bathrooms, humid climates, and cross-border shipping routes can expose weak materials quickly. One cosmetics client I advised had a beautiful matte compostable mailer, but the inner product box was susceptible to swelling. We switched to a stronger hybrid structure and reduced damaged-in-transit claims by 18% over the next quarter. That number mattered more than the packaging poetry. The replacement spec used a 3.5 mil hybrid film and a stronger adhesive line, and the complaint curve dropped within six weeks.

Here’s the checklist I’d use before placing an order after reading this review of biodegradable mailers:

1. Confirm your product weight and dimensions.
2. Ask for a sample with your actual insert or product.
3. Test the seal after sitting 24 hours in a warm room.
4. Check for corner splits after a simple drop test.
5. Verify whether the disposal claim is industrial compostable or home compostable.
6. Ask for MOQ, unit cost, lead time, and print setup fees in writing.

Our Recommendation: Which Biodegradable Mailers Are Worth It

My recommendation from this review of biodegradable mailers is pretty simple. If you want the best overall balance, choose a hybrid Compostable Poly Mailer or a strong PBAT-based mailer. If you want the prettiest presentation, pick a kraft mailer with a compostable liner. If you want the lowest starting cost, starch-based options can work, but only if the supplier gives you real consistency and documentation. And if someone tries to sell you “eco” packaging without showing certification papers, I’d walk. Not because I enjoy being difficult, but because the paperwork usually tells the truth the sales deck won’t. A supplier in Guangzhou once tried to substitute a brochure for a test report; the order did not move forward, and that decision saved both time and returns.

For brands that care about branding as much as shipping performance, the premium route can be worth it. I’ve seen customers keep a package because the mailer felt intentional and looked credible. That matters. But don’t buy presentation at the expense of returns. A mailer that looks expensive and fails in transit is just expensive failure. I’d rather have a plain mailer that arrives intact than a gorgeous one that turns into confetti somewhere between sorting hub number two and the customer’s front door. In one London rollout, a kraft option added $0.09 per unit but improved customer feedback enough to justify the spend; in another, the same upgrade was pure vanity because the product was already protected inside a rigid box.

Here’s the route I’d take for most clients after this review of biodegradable mailers: request 2 to 3 samples, compare them in your own packing flow, and run them through a simple stress test. Pack 50 units. Store them overnight. Drop a few. Push them through your normal dispatch process. Then choose. I’ve negotiated enough with factories to know that the best pitch is always a sample that survives your own warehouse. If the packaging can’t make it through your team’s daily chaos, it doesn’t belong in production. For custom orders, I’d expect 12–15 business days from proof approval before the goods are ready to leave the factory in Dongguan or Foshan.

My bottom line: if your shipment is light, your route is reasonable, and your brand wants a greener story that feels real, a good review of biodegradable mailers should steer you toward PBAT or a hybrid structure. If your shipment is sensitive, heavy, or goes through rough transit, you may be better off choosing a stronger conventional structure or a paper-based format with verified performance. Green is nice. Arriving intact is nicer. Honestly, that’s the whole argument in one sentence. If you need one number to remember, remember this: a cheaper mailer that causes a 2% increase in returns is not cheaper at all.

What does a review of biodegradable mailers need to answer?

A useful review of biodegradable mailers should answer the questions buyers actually face: which material holds up best, which claims are verifiable, and which option fits the product and packing flow. It should also address sustainability terms clearly, because “biodegradable” and “compostable” are not interchangeable in practice. If the article skips seal strength, water exposure, and MOQ, it is probably too shallow to guide a purchase. A buyer shouldn’t have to decode buzzwords just to figure out whether a mailer can survive a warehouse on a hot day.
