why sustainable workwear is the wrong question
by Part Wild
·
walk into any workwear aisle now, online or otherwise, and every pant has a story about the planet stapled to it. organic this, recycled that, a badge, a number about litres of water.
we make cotton and cordura pants in brooklyn, and we still think sustainable is close to a useless question, because almost every number holding it up was modeled instead of measured, and the one thing that genuinely moves a garment’s footprint never appears on the tag.
a garment’s footprint is mostly decided before you put it on
a 2024 study in science of the total environment modeled one pair of jeans across its whole life and found that the fast-fashion version cost about 11 times more carbon per wear than the same jeans bought to be kept. the split inside that number is the interesting part. about 91% of the impact came from making the jeans and moving them around the world, and only a sliver came from washing them.
so the footprint is set at the mill and the sewing floor and the container ship. after that, the only lever left is arithmetic. one pair of pants divided by 40 wears is a big number, and the same pair divided by 900 wears is a small one, and no certification on earth changes the denominator. you do.
the big fashion numbers get worse every time somebody repeats them
the line about fashion being the second most polluting industry after oil traces back to no study at all, and in 2020 nature reviews earth and environment printed a formal author correction striking that claim from a paper it had appeared in, calling it an editorial error. the 10% of global emissions figure is not much sturdier. the published range runs from roughly 2% to 8%, and the estimates disagree with each other by nearly three to one, because they cannot agree on whether to count shipping, or the use phase, or your dryer.
it gets closer to home than that. in 2022 norway’s consumer regulator ruled that a brand advertising organic cotton with higg index data was misleading shoppers, and that june the sustainable apparel coalition pulled its consumer-facing higg labels off retail sites worldwide and commissioned an outside review of the method. the famous 87% less water claim did not survive the look. organic cotton mostly gets grown where it rains more, which is a fact about geography.
our cordura sheds microplastic in the wash, and that is the small number
the task pant and the task jacket both use cordura nylon, so the microplastic question lands on us and we are not going to route around it. nylon sheds fibre in the wash. cotton sheds too, by weight sometimes more, though what nylon releases is harder to catch in a filter.
here is the size of it. a 2024 paper in nature communications put synthetic garments thrown away at end of life at 81% of the apparel industry’s plastic waste, while microfibres shed in washing came to under 1.5% of its plastic leakage. the washing machine is a rounding error next to the dumpster. which means the thing that actually keeps nylon out of the ocean is a garment nobody throws out, and that is a construction problem, a fit problem, and a repair problem before it is a fibre problem.
cotton is the shortest-lived fibre in the wardrobe surveys, which is why we blend it
a 2020 study in sustainability logged nearly 47,000 real garments across five countries and found cotton items were kept fewer years than any other fibre group, with synthetics held about five months longer and wool over a year longer. that is an inconvenient finding for everyone selling cotton as the responsible choice, us included, and it is also the reason we build the way we do.
cotton is what makes a pant feel like something you want on your legs at 6am. nylon 6,6 is what keeps the knee from going. invista, which makes cordura, puts a cotton-plus-nylon build at four times the abrasion resistance of a comparable-weight cotton duck. we put the cotton where your skin is and the nylon where the ground is, and the whole point of the blend is to stop the cotton losing that survey.
price does not predict how long a pant lasts
a 2025 uk lab study in cleaner and responsible consumption abraded 17 pairs of jeans bought off the high street and found no relationship between price and durability. the weakest pair, at about £33, gave out after 15,000 rubs. the toughest, at £13, took 105,000. seven times the life for a third of the money.
$198 does not buy durability by itself. it buys durability when somebody spent it on the cloth and the sewing rather than on the campaign. since the price tag tells you nothing, check the garment:
- turn it inside out and read the seams. you want the seams that take load doubled and locked, and enough seam allowance left inside that a tailor has something to grab.
- find the reinforcement and see if it is in the right place. a tough patch on the hip is decoration. tough cloth at the knee, the seat, and the pocket bags is a decision.
- ask who fixes it. a brand that cannot tell you how a blown crotch seam gets repaired has not thought about year three.
work pants die at the seams and the colour long before the cloth gives up
when researchers inspected clothing that uk charities had rejected as unsellable, work trousers failed differently from everything else: about half showed fabric breakdown like fraying and thinning, and 42% had holes in their seams (cooper, hughes and claxton, plate, 2015). across the wider pile, close to 70% of rejected garments had a colour problem, usually fading.
read that as a build list. seams are the first thing to go, so seams get the attention. colour is the second, so dye that goes grey in a season is a durability defect wearing a marketing hat. and both failures are repairable, which is the argument for buying a garment somebody can actually fix. an LSd̶T with a small hole is a shirt with a small hole. a bonded, glued, unpickable technical shell with a small hole is trash.
how the four common work cloths compare on staying alive
every work pant solves the same problem, keeping cloth on your body while the world sands it off, and the answers cluster into about four cloths. here is how they compare on what the body is, what it does under wear, and what it costs you.
| the cloth | what the body is | what it does under wear | what it costs you |
|---|---|---|---|
| organic cotton with cordura nylon (our task pant) | long-staple cotton body, high-tenacity nylon 6,6 at the wear points | four times the abrasion resistance of comparable cotton duck, per cordura’s maker | $198, and the cloth is slow enough to make that we run out of sizes |
| 100% cotton duck | heavy plain cotton canvas, the traditional work body | breathes and softens well, and cotton is kept fewer years than any other fibre group | cheap and sold everywhere, goes at the knee first |
| all-synthetic technical cloth | polyester or nylon face, often coated or bonded | takes abrasion, dries fast, and gets kept about 5 months longer than cotton | plastic all the way through at end of life, and bonded seams resist repair |
| selvedge denim | rigid woven cotton, made to be patched into | breaks in hard, and lab abrasion on jeans ran from 15,000 to 105,000 rubs with no link to price | stiff for months, hot in august, and only works if the repair actually happens |
frequently asked questions
is organic cotton actually better for the environment?
on pesticides and soil, organic farming has a real case. on water, the popular claim fell apart under review, because organic cotton is largely grown in rainier places and yields less per acre, so the saving mostly cancels out.
do i need to wash work pants less to make a difference?
washing less helps a bit and it helps your pants more, since heat and detergent are what fade the colour and weaken the fibre. it is a small lever next to how long you keep the garment, so wash cold, hang dry, and spot-clean what does not need a full cycle.
can cordura nylon be repaired?
yes, and that is part of why we use it. woven nylon takes a patch and a stitch the same way canvas does, and any tailor who handles work clothing can close a seam or reinforce a knee.
does buying secondhand fix the problem?
it helps, and it is not a one-for-one swap. studies of secondhand buyers find that buying used does not fully replace buying new, and clothes bought secondhand tend to get fewer wears from that second owner than a new garment gets from its first.
what certification should i look for on workwear?
none of them tell you how long the garment lasts, which is the variable that matters most. ask what the cloth is by name, where the reinforcement sits, and who repairs it, then compare that against what you are being charged.
the question with an actual answer is how many times you will wear it
sustainable is a claim about a garment’s past. wear count is a claim about its future, and it is the only one you can influence after you pay. one uniform you put on without thinking, worn until the knees need a patch and then patched, beats any badge on any tag by a factor the jeans study puts in double digits.
that is also a harder thing to sell, because it cannot be printed on a hangtag. it has to be built into the cloth, the pattern, and the seams, which is the only place we have ever been willing to spend the money.
how part wild puts cordura where a work pant dies first
we built the task pant around the wear count instead of around a claim. organic long-staple cotton for the part that touches you, cordura nylon at the knee and the seat and the pocket bags, cut with stretch so it feels broken in the first day, at $198 in sizes 0 to 5 and four colours. the task jacket is $275, le vest is $245, and everything ships from brooklyn in about 7 business days.
we did not test this with a lab report. we wore the first run for three years, then donated a batch to a farm for a whole season, and the farmers came back and bought more. people finish a two-week masonry course where everyone else’s pants tore and theirs did not. there are two of us plus a few specialized contractors, the cloth is a nightmare to make and gets sewn in portugal, so the line is small and we are often out of your size. that is the actual trade you are making.
part wild makes uniform judged on materials, design, and construction, which is what decides how many wears you get out of it. sizes run 0 to 5, it ships from brooklyn, and if you want to know what is in the cloth before you buy, shoot us a note.
