You can't do a mission from California to Cape Flattery on one tank of gas, but you can do it with just one suit. Made with high-quality neoprene that meets our rigorous standards for strength, warmth and stretch, the new Water Heater Hooded Vest offers additional insulation for your head and core as you roll into the cold and windy conditions of the Pacific Northwest. Built to be worn under a wetsuit, the vest extends any wetsuit's thermal range. The hood has a warm and quick-drying micro-grid thermal lining (made with 67% all-recycled polyester content); the body has a high-stretch 100% recycled liner; and the entire garment has an exterior made of water-resistant, durable 88% recycled polyester/12% spandex. An outer neck baffle sits over the wetsuit neck to prevent water entry and the adjustable face opening has a cinch-locking elastic cord. Seams are glued and blindstitched for durability and comfort.
