Every piece of clothing in our women’s activewear collection is designed to fit your body and move with you, however you need it to. Never think about struggling with your straps or out of your sports bra again. Loose leggings that keep slipping? Not here! Wedgies? Not with our workout undies!
Our workout clothes are designed with innovative moisture wicking technology, removable cups, convertible x-back straps, and super comfy, never too tight high rise waistbands. Your workouts will be smoother and more comfortable than ever with our collection of sports bras and leggings. We offer three moisture wicking lines of women’s activewear for low, medium and high impact workouts: Muse, Flex, and Kinetic. Each line is made for your body and your performance needs in an inclusive range of sizes from XS-3X. No matter your size or active level, there’s something for you.
