Designed for additional warmth and protection, the Thermal Polarclava with its smooth outer lining is the perfect layer for under your waterproofs in extreme conditions. Featuring our recycled polyester thermal fabric, the Thermal Polarclava is created with wicking yarns and a microfleece interior for exceptional comfort. In addition the polarclava is anatomically shaped with a hood that can be easily pulled back when full coverage is not needed, a great addition when out on the water.
