Flex - Seamless Knit Activewear

Best Seamless Activewear at ThirdLove

At ThirdLove, we believe all women deserve to be supported in style during workouts. You don’t need to sacrifice beauty for comfort - now you can have both! That’s why we’ve designed Flex activewear sets that provide enough compression to make you feel comfortable and confident while exercising. Made with high-quality fabrics, our workout sets are functional and feel great against the skin, providing moisture-wicking properties when you sweat it out at the gym or outside.

Different Types of Leggings, Sports Bras & Racerback Bras for Women

Our Flex Seamless Racerback Sports Bra will gently hug and press your boobs, keeping them from bouncing and moving around when you get active. With engineered knit zones, this bra will sculpt your bust and shape it to look fabulous while providing extra support and comfort. It’s one of the best sports bras for activities like jiu-jitsu, cross-training, and meet-up workouts with friends. ThirdLove’s Flex Seamless Compression Legging offers just the right amount of compression to make you feel comfy all day. This design creates a seamless silhouette, giving you all the support you need while exercising or going out. It’s also a great base layer and can be worn for activities in colder temperatures. The high wasted knit structure will smooth you out while holding up your belly (which is also perfect for pregnant women).

How Should the Flex Collection Fit?

Sports bras for women fit a little differently than the regular ones. Look for a snug fit that fully supports your breasts and gives enough compression, but make sure you can still fit two fingers under the straps. The sports bra shouldn’t be too tight or restrict your breathing. It’s also good to move around in your sports bra to test it - raise your hands and do a few movements to see if the bra rides up. If it does, you might need a different size. Workout leggings should hug your legs like a second skin. If there are wrinkles or bagginess, you’re probably wearing a size that’s too big. Ensure they’re not too tight, and you can move around freely.

Flex Activewear for Medium Impact Workouts

Our Flex line of workout leggings and sports bras are made with breathable, body sculpting fabrics, designed to offer support in all the right places. Think compression that’s never too tight or constricting. You’ll love our Flex Seamless Racerback Sports Bra, Flex Seamless Bike Short, and our high rise, high comfort Flex Seamless Compression Legging for all of your favorite workouts like cross-training or long weekend-ing. Available in bundles and sizes XS-3X.

Whether you’re going to the gym, a crossfit class or need freedom from constricting activewear, we’ve got the active support you crave. Try activewear by ThirdLove and join the millions of women changing the game, making workouts comfortable. You’ll wonder how you ever worked out without it!
