The extremely popular Blue Seventy Thermal Cap has been re-designed for 2021 with an adjustable chin strap. High quality Yamamoto neoprene paired with our thermal zirconium lining creates a cozy cover to keep your head warm on the coldest swims.
Stay warm with the Blueseventy thermal skull cap. 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.
