Why We Make The Best Underwear

You'll Notice The Fabric The Second You Touch It

When we first worn bamboo viscose, we couldn't believe fabric was could be so soft.

We decided to make underwear from USDA organic bamboo, put some nerd-inspired patterns on them, and cut and sewed them to be the best fitting underwear you'll ever experience.

    Backed my first pairs (trunks) on Kickstarter, and just ordered another three pairs! I’ve been looking for a great pair of undies for a couple years now since I put out a ridiculous amount of core body heat and sweat a lot in hot weather. That makes non-breathable underwear types like cotton out of the question since they don’t cool well and don’t wick moisture, leaving me either with hot twigs and berries or a swampy butt. Bad news either way and it’s been a slog finding undies that fit my needs.

    These check all my boxes. They wick moisture away well and have kept me quite cool while going through a very hot summer in Sacramento, CA area (98s-105s, very few clouds), The color quality is excellent and I hardly notice I’m wearing them at all. A+’s all around!

    My husband loves how soft and comfortable these are. We bought some on the kickstarter and came back and bought more already. Can’t wait for more designs.

    Bought a pair of these (in “cosmic”) for my partner through Kickstarter & they just chose to wear them for a 24hr long day of flights/travel. So I’mma guess that we’ll be ordering more as soon as there are more fabric choices!
