This top is cute enough to wear with jeans (oh, and we've done that!), but is made of a lightly textured, high performance functional dry knit fabric meant to quickly wick away sweat. We designed this top to hold up to your sweatiest runs or HIIT classes. And, the flat seam construction means that there is no chafing against your skin. Fabric: 88% Polyamide, 12% Elastane
