Zero waste meets zero dye. A match made in heaven, on Earth, and a best-selling style.

Seriously comfortable, all natural (read: zero plastic fabric), breathable bikini brief in Undyed. Our founder couldn’t find this fit in an all cotton option so she designed one that disappears on you. Seriously. The feedback is that you forget you're wearing them! We picked flat lock seaming because it doesn't create seam allowance that digs into your skin. The plastic-free Pima Cotton rib stretches naturally and comfortably around any curves. Ethically made in Peru on a living wage.

Undyed = better for your skin and better for our planet. Undyed fabrics require significantly less resources and processing than their dyed counterparts. Each of our super soft, natural Undyed Bikini Briefs saves:

3L water
0.3kg steam energy
1kg CO2 electricity emissions

Ships in 3-7 days.

Amazing underwear

I have bought more than ten pairs of these underwear and I love them. The quality, fitting and material is great. They are very soft and I like the fact that they are undyed. My hope for the future is that the material should be organic, the rest is just perfect! Thank you very much for making them!

Incredibly comfortable. Good for the body and the planet. It's the only brand I want to wear now, so I will be ordering more. Looking forward to trying other products from this innovative brand!

Eco-Friendly and Happily No-Frills

Super comfortable. The no frills (bows, lace, patterns) "line" and neutral color especially great under summer clothes.
