Engineered for sun, surf, and serious fun.
The Under Armour Biomolecular Swim Set includes a long sleeve performance shirt and matching volley shorts—designed to handle every splash, dive, and cannonball in comfort and style. The lightweight long sleeve top features UPF 50+ sun protection and a smooth knit fabric that moves with them from sandcastle duty to swimming laps.
The matching volley shorts are made with a suede-like, quick-dry material that’s both salt- and chlorine-resistant, so color stays vibrant wear after wear. A built-in mesh brief adds breathability, while the encased elastic waistband ensures a secure, pull-on fit for all-day movement.
