Most performance underwear is made from toxic plastics. Yours doesn't have to be.
Through every squat, sprint, stretch, and step, your underwear may be releasing toxins.
MINDFUL MOVEMENT
What touches your skin matters most when you sweat.
Heat, sweat, and friction are part of every workout. As your body warms up, skin becomes more permeable and sensitive. What sits against your skin during movement matters more than most people think. Yet that layer is often made from synthetic fibers like polyester, nylon, and spandex, finished with dyes and chemical treatments, sitting directly against some of the most delicate, absorbent skin on the body.
Underwear designed for life in motion.
Breathes when you sweat
