tyvek. a material you already know - you just don't know it yet.
looks like paper, feels like paper, but it's plastic. nasa has worn it since the sixties, surgeons wrap instruments in it, festivals turn it into wristbands. and we make wallets from it - 9 grams empty, about 30 loaded.
every wallet looks the same inside. a few cards you use every day. a few banknotes. a loyalty card from a coffee shop - "every tenth free", one stamp. and a receipt that's been sitting there for who knows how long, and you don't even remember why. classic.
and it probably weighs more than it needs to. a standard leather wallet with a full set of cards and cash is 100 to 160 grams - and most people take that weight as given. (we did too, until we started trying a different way.) it can work completely differently.
there's one material that solves the problem. it's a bit strange, and it makes sense to spend a few minutes with it before you buy something made from it.
it's called tyvek. and you probably know it already - you just don't know it yet. maybe that festival wristband you can't get off without scissors. but that's just the start. nasa wears the same material into cleanrooms where satellites get assembled. formula 1 drivers have it in suits that have to survive fire crashes. and fashion designers use it for collections hanging in the museum of modern art in new york.
and we make wallets from it - thin, light, rain-proof, and better-looking than leather.
you grab it, you want to tear it. you can't. and that's when you realize you don't hold a material like this every day.
on tyvek, first time in hand
what is tyvek, if not paper
short version: it's plastic. wait before you close the tab.
dupont, 1955. someone was working on something else entirely and accidentally figured out how to spin polyethylene into fibres as thin as a hair and press them into a sheet. the result looked like paper. except you couldn't tear it.
it took another twelve years before anyone could work with it in practice. tyvek has been on the market since 1967. today it's under roofs, in hospitals, on spacecraft, and at festivals.
technically: high-density polyethylene, hdpe. same category as pet bottles. practically: a strange thing. you feel it the moment you grab it. it looks like paper, feels a little different, and when you try to tear it, you realize you can't.
why tyvek
leather was never on the table. two rules we set for ourselves at the start - no animal in the process, everything recyclable - decided what we could use. tyvek met both. and it does five things other vegan alternatives can't do at once.
water. nothing. no trace.*
really. a wallet full of cards and cash, like new after drying.
where tyvek can't fail
wallets weren't the plan. tyvek was developed for places where someone's life or a billion-dollar machine depends on it. your back pocket is pretty easy by comparison.
apollo missions
tyvek was part of the program that sent a man to the moon. it protected sensitive components in the assembly from contamination before launch.
fukushima and chernobyl
workers entering radiation zones wear tyvek suits. they catch radioactive dust and are disposed of as waste after each shift.
sterile surgical packaging
hospitals wrap instruments in tyvek - it lets sterilization steam in, keeps bacteria out.
roof membranes
tyvek homewrap is standard under facades across europe. inside walls, it's built to last decades.
your pocket
and now here too. after moon missions, nuclear zones, and operating rooms, a wallet felt like the logical next step.

yes, tyvek is technically plastic. we're not hiding from it.
at its core, tyvek is polyethylene. which means yes, technically - it's plastic. we're not going around it.
we could write "innovative non-woven material" and hope no one asks. but that's not us.
we know why we've come to fear plastic in recent years. single-use packaging, bags, bottles - things made in a minute that then sit for centuries in landfills or oceans, breaking down into microplastics, never fully gone. that fear is fair. tyvek just isn't that kind of plastic.
tyvek isn't single-use. it's designed to last years. it doesn't break down into microplastics. it contains no plasticizers or binders, so nothing leaches into the environment - it's inert, it just sits there. and when you hand it in for recycling, it comes back into circulation in a different form and keeps going.
leather would be the traditional choice. for us it was never on the table - behind it is an animal that didn't choose this. tyvek let us make wallets without that compromise and stay with our own rules.
