Under Armour Siro Women's Vest

The Under Armour Siro Women's Vest provides maximum comfort for your best performance.

In a loose, generous fit, the Siro Vest provides relaxed comfort. The Siro fabric gives greater stretch and recovery, an ultra soft feel and breathable performance. It allows cool air to permeate and hot air to escape, preventing an intolerable heat build up. The material wicks sweat away from the skin onto the outer layer where it can be evaporated, leaving you feeling cool, dry and comfortable. Enriched with anti-odour technology, the vest prevents the growth of odour causing microbes to keep you feeling fresh. The shaped hem delivers enhanced coverage, whilst the super-skinny racer back design unlocks mobility for a large range of motion.
