The Gamut Sport Top delivers high performance, a great fit and 25-UPF-sun protection, with a blend of 91% polyester (82% recycled) and 9% spandex seamless variable knit fabric combined with mesh zones to optimize breathability, ventilation and comfort. A supportive internal sports bra won't bind, and the top's nearly seamless construction won't chafe. With Gladiodor odor control for the garment, and tag-free construction for itch-free comfort.
