The Problem
Most Activewear is Made of Plastic.
And the problem with traditional plastic activewear is that it...
Leaches Harmful Microplastics
Every time you wear polyester, millions of microplastics shed from the clothes onto your skin and into the air around you. Do you really want that on your skin?
Made With Toxic Chemicals (Like BPA)
A shocking study found that 100+ activewear brands contained high levels of endocrine disrupting BPA - some even have 40x the legal limit!
May Have Fertility Impacts
A groundbreaking study showed wearing polyester underwear made men azoospermic - meaning their sperm count dropped to zero.

Repped by thousands of real people
See why 50,000+ real customers have ditched their polyester gym shorts...
I was skeptical natural fibers would perform as well as polyester, but I was wrong...
Been trying to avoid plastic clothes but wasn't sure natural fibers could compete. I mean wool and cotton for the gym? But happy to say I was wrong about these - they're surprisingly stretchy & fit very similar to my Lulus. Will be buying more.

Wanted to avoid plastic clothes but didn't want to sacrifice comfort or function - these do the job
I don't want to be wearing plastics for my health but wasn't ready to give up my synthetics. However, I've been surprised that these have held up, wicked sweat and fit just as well.
Connor B., New York City
Happy to not be wearing plastic in the gym or sauna anymore...
Yes they're expensive, but I'm happy to not be wearing plastic to the gym and in the sauna anymore. They're also surprisingly stretchy - very different than many other natural brands.
