no frills. no fuss. all fluff.

at cotton bum, we believe that what you wear closest to your skin should be the cleanest, softest, and most natural thing in your wardrobe. that’s why we’re devoted to making underwear from 100% certified organic cotton—no synthetics, no toxins, no compromises.

our skin is our largest organ, and it absorbs what we put on it. most conventional underwear is made with chemical-laden dyes, synthetic fibers, and plastic-based fabrics that can trap heat and irritate your skin. we think you—and your bum—deserve better.
