87% 37.5™ polyester, 13% spandex, thermoregulating UPF 50+ 

The activated particles in Cocona™/37.5™ fabric increase the surface area by up to 800%, resulting in outstanding evaporative cooling and UV protection. The climate control fabric retains warmth if you start cooling down or releases warmth if your core body temperature starts to rise. The sun protection never washes out.

A garment’s greatest environmental impact comes from its care after being purchased. Wash only when necessary in order to save water.  Machine wash warm, tumble dry low.
