The Thermal Skull Cap takes our popular Neoprene Cap to the next level. By incorporating a hollowed wool liner composed of yarn fibers (zirconium) on the internal jersey we reduce water absorption which helps create an extra boundary layer to protect against heat loss. For those truly chilly swims stay warm in blueseventy.
