The Thermo Top SS Men bridges the gap between Neo Tops and Rashguards. Thermo Tops are quick to dry, velvety soft, warm, and fantastically robust on the external surface. With multi-purpose functions, they can be used as a thicker substitute for a Rashguard on cooler days to protect you from the dreaded wind-chill, skin chafing, and harmful UV rays. In colder waters, they can be worn under your wetsuit for additional warmth.
