game-changing underwear made for gettin' sweaty

Our mission is to disrupt the women's active underwear market by replacing poorly performing, polluting, and landfill-destined petroleum-based polyester microfibers, with sustainable, natural, moisture-wicking, and thermo-regulating Merino wool.

Our products, which we call "Performance Innerwear", are created by active women specifically for a woman's body during physical activity and feature GLDNspun Tech seamless knitting.

Unlike polyester-based gear that currently dominates the marketplace, our products are made using Merino, a biodegradable fiber that quickly and effectively moves moisture away from the body, eliminates funk, and regulates body temperature. Simply stated, Performance Innerwear keeps active women Boob-Sweat Free, Swamp-Ass Free, and Funk-Free regardless of how hot and sweaty things get.

We're the triple threat of women's performance underwear. We deliver Performance, Comfort and Sustainability!

Play Fierce, Stay Golden.

Game-Changing Products

unmatched performance

Stay cool, comfy, and dry, all day, every day, regardless of how hot and humid it gets. We use seamless knitting technology that allows our Innerwear to move with you. It doesn't ride up, slip down, or give you a wedgie. You'll forget you're even wearing it.

ALL DAY COMFORT

...regardless of your game plan. Whether it's hot yoga, hiking, running, walking, biking, working, traveling, or recovery, you will love how comfortable and fresh you feel. Performance Innerwear keeps you boob-sweat free, swamp-ass free and funk-free all day long!

EARTH FRIENDLY

Our OKEO-TEX and Reach Certified products are WAY better for our planet than petroleum-based polyester microfiber gear. Merino is a natural, biodegradable fiber that is 100% renewable. Sheep produce new fleece over and over and Merino wool decomposes naturally in soil.
