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.

"The material is very unique, but super soft and stretchy. The colors are gorgeous and I love that they have the logo on the back on the sports bra. Highly recommend these for everyday training and sports! I will be repurchasing!"
"Two reviews: the sports bra is the most comfortable I have worn!! As an avid runner I am looking for something that will provide enough support but not suffocate me. Also, the customer service was exceptional. My package got lost and they sent me a new one right away. I will definitely be ordering more colors soon."
"I was pleasantly surprised with this bra. I usually look for high neck bras to keep everything in place. However, this bra has exceptional hold and I wasn't scared that I would have any surprises during yoga class or in high intensity workouts. For context, I am 36C."
"Love the fit and color of this sports bra. I wear between a small and a medium and the medium fit perfectly. My only complaint is that the racer back strap is a little high on the back of my neck. It’s still very comfortable but I prefer it to hit a little lower. Overall- excellent!"
"This is a lovely, no-fuss, high quality sports bra that washes well (I use dryer sometimes and also hang dry it). I purchased another one in a different color. Just the right amount of compression. I like that there are not removable pads, which never seem to wash well."
"I’ve been slowly changing out my workout clothes to brands made without forever chemicals. That’s how I found Definite Articles. I love them! The shorts are soft and stay put. This sports bra is my favorite. It’s also soft and breathable. I live in Hawaii and train in the heat and humidity so breathability is a big deal. I’m so glad I found this brand. I’m going to order two more of this product right now!"
"Super comfy and lovely fit. Great support. I’m a 36 D and it feels really comfortable. I ordered a large but am losing some weight so went back and ordered a medium too. Love this. Will get lots more"
"Great bra, feels like I have nothing on and I like that it's free of chemicals. I'm very small chested and the XS fits perfect and doesn't totally flatten me out like other sports bras I've tried"
"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!"
