KinswaJoin the waitlistPolyester is plastic.
Most clothing sold today is spun from crude oil. Polyester, nylon, acrylic — plastics by another name. Every wash sheds fibers that end up in rivers, in oceans, and eventually in us.
Kinswa exists to take the plastic out of getting dressed. We make clothing from natural fibers — led by hemp, the toughest of them all — grown in soil and returned to soil.
What we believe
- Clothing should be grown, not extracted.
- A shirt should outlast its trends — and still return to the soil.
- Durability is sustainability. The greenest garment is the one you keep wearing.
- Education beats marketing. Read the label; we'll teach you what it means.
Hemp holds up.
Hemp is one of the strongest natural fibers ever spun into cloth. Sails and rope were hemp for centuries — the word canvas comes from cannabis.
As a crop, it asks for little. It thrives mostly on rainfall, crowds out weeds without pesticides, and leaves the soil better than it found it.
As a fabric, it breathes, blocks sun naturally, resists mold and odor, and softens with every wash — without shedding a single plastic fiber.
| Property | Hemp | Cotton | Polyester |
|---|---|---|---|
| Source | A crop | A crop | Crude oil |
| Microplastics in the wash | None | None | Every wash |
| Pesticide demand | Rarely needed | Heavy | None — it's plastic |
| Water demand | Low, mostly rain-fed | High | Low, but petroleum-based |
| Wear over time | Softens with use | Thins and tears | Pills and clings |
| End of life | Returns to soil | Returns to soil | Persists for centuries |
Wear plants.
No polyester. No nylon. No plastic thread holding a “sustainable” shirt together. All of it grown, all of it honest.
