GOTS Certified Organic Cotton Underwear, Made to Feel Better.

What touches your skin matters.

Stone.kin creates organic cotton underwear for men and women using buttery soft, breathable GOTS certified organic cotton. Designed for everyday comfort and made with considered materials, our underwear feels naturally soft against the skin while giving you the stretch and freedom to move.

From men's organic cotton boxer briefs, trunks and briefs to women's organic cotton underwear, bras, bralettes, thongs and bodysuits, every piece is designed around comfort, simplicity and a more considered approach to what you wear closest to your body.

Why Choose GOTS Certified Organic Cotton Underwear?

GOTS, the Global Organic Textile Standard, is one of the world's leading standards for textiles made with certified organic fibres. It sets strict requirements across textile processing, including environmental criteria, chemical inputs and social responsibility.

For Stone.kin, that means starting with certified organic cotton and making underwear with greater consideration for both the people who make it and the environment it comes from.

Our fabric is made from 95% organic cotton with 5% elastane, giving you the natural softness and breathability of cotton with just enough stretch for a comfortable everyday fit.

Soft, Breathable and Made for Everyday Comfort.

Underwear sits against your skin all day, so fabric matters.

Our signature organic cotton rib is soft, breathable and comfortable from the moment you put it on. The small amount of elastane helps each piece move with your body while maintaining its fit, creating underwear designed to feel good without relying on synthetic-heavy fabrics.

Stone.kin styles are also OEKO-TEX® certified. OEKO-TEX® STANDARD 100 certification means textiles have been tested against requirements covering harmful substances, with stricter requirements applying to products worn directly against the skin.

For anyone looking for organic, natural or non-toxic underwear alternatives, it is another layer of reassurance about what you're putting next to your skin.

Organic Cotton Underwear for Men and Women.

Our collection includes organic cotton boxer briefs, trunks and briefs for men, alongside organic cotton briefs, thongs, bras, bralettes and bodysuits for women.

Each piece brings together natural comfort, considered construction and Stone.kin's distinctive palette of earthy, understated colours.

No overcomplication. Just buttery soft organic cotton underwear designed to become part of your everyday ritual.

Better Materials. Better Every day Basics.

Choosing GOTS certified organic cotton underwear isn't about sacrificing comfort or style for sustainability.

It's about expecting more from the things you wear every day: soft natural fibres, thoughtful design, responsible standards and underwear that simply feels good against your skin.

Mindfully made. Creatively driven. Naturally comfortable.
