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.
Certified by ECO PASSPORT by OEKO-TEX®.

"Out of three different brands of non- toxic athletic wear that I have tried, Definite Articles is the best! The material is soft and comfortable and the fit is spot on. This brand has great quality products that won't let you down when working out. They stay put and hide sweat. The athletic bras and performance tees are my favorite."
"I really love the fit and the durability of all of their clothing. They are lightweight and free of micro plastics that are found in almost all the athletic brands. The colors don’t fade."
"Perfect tee, great length, and has a more cotton feel then performance fabric."
"This shirt fits great, is breathable and so soft! Absolutely love it and the fact that it is zero toxins!!"
"Great Fit, very very soft and has kept its shape. I wish there were more colors"
"So happy to find a soft yet breathable shirt for workouts. The length of the shirt sits perfectly right below the waist and moves great during a workout. Super cute and versatile!"
"Basic but perfect. WIll buy every color you make. Fits true to size. Holds up in the wash. Breathes and doesn't hold a stink."
"I have the navy and it’s the prettiest color. Looks great with the black leggings. Washes well"
"Love this workout top and the fact I don’t need to worry about microplastics or weird chemicals! Super comfy material. Great for working out or just lounging. It does run small though - I am normally a large, sometimes XL. Ordered an XL and it’s pretty snug! Still cute and comfy though. But definitely size up 1-2 sizes if you want it looser."
"Love the fit & quality of the fabric. I am looking forward to purchasing more. I feel so much better knowing that I have non-toxic activewear."
