Built on CiCLO® biodegradable fiber.
CiCLO® is built into our recycled synthetics to do two things: shed fewer microplastics in wear and wash, and biodegrade rather than linger. Independent testing shows CiCLO treated fibers biodegrade in under four years — so they don’t add to long-term microplastic pollution.

"I am overjoyed with the bra, biker shorts and racer back t shirt I recently purchased and put to the test in the 100 degree hot room. Comfortable, great fitting, moisture wicking and non- toxic is all I can ask for. I will be purchasing more ASAP!"
"I have a relatively slim frame and a large bust and I have never liked many sports bras. I was SO excited to find something that is not only clean materials, but also actually provides great support for high intensity workouts and is comfortable enough to spend the whole day in without giving the uni-boob look. I highly recommend this bra!"
"I got rid of all my older sports bras in favor of more natural or toxin free options. Of the brands I’ve tried so far, this is by far my favorite. I don’t notice it while I’m running which is exactly how a sports bra should be. Fits true to size. I’m planning to buy more."
"I absolutely love these sports bras! I jump for a living as a fitness instructor in our boots in Boston Jumps class and on trampolines. Hands down perfect support and fit."
"I really love these yoga clothes they are my favorite so far they don’t show sweat and yet they are non toxic they also look good after a work out unlike other brands! Thanks !!"
"I love this sports bra! It's incredibly comfortable, supportive, and perfect for Pilates. The fabric is soft, the fit is flattering, and I appreciate that it's made with nontoxic materials. My only wish would be the option for removable cups, but that's just a personal preference. Overall, it's a great-quality sports bra, and I'm really happy with my purchase!"
