Before heading to your next yoga class or HIIT session, slip on the Flow Y sports bra from athleisure label lululemon. Why? Because it's made from the brand's signature Nulu fabric, a breathable textile that's imbued with four-way stretch technology, meaning you can fall into Downward Dog easily. Oh, and did we mention that this racerback style is also sweat-wicking and boasts padded cups for extra security, too?
