Nylon 10% Elastane Prism² does – and this sports bra is a prime example. Styled in sleek black, it’s crafted from a stretchy nylon blend and features ultra-supportive, sweat-wicking technology that promises to keep you cool and dry while you’re sweating it out. Chlorine-resistant, you can wear it as a bikini top, too, or alternatively, as a comfortable under-garment for everyday.
