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.

Wear these to bed and out and some of the most comfortable underwear I have worn. Great for anyone. Way to go TBF. Cheers

comfy and earth friendly? sign me up!

absolutely love my TBF underwear! i originally bought a three pack (in white) and am working on replacing my whole underwear drawer with these bikini briefs. the fabric is SOOO soft and absolutely lovely on the skin. i also love how these are undyed -- though it makes me think they might just be ripe for some natural dyeing experiments! and of course i am SO excited to have them be part of the circular economy when it's time to put them to rest. i'm trying to convince everyone i know to give these a try -- everyone i know who i'm close enough with to talk underwear choices at least haha!

These are great! Within minutes of putting them on, I forget they are there which is exactly what I want out of my underwear. I find this fit is a bit more flattering for us shorter gals than the thong.
