The Surface Vest is dual-sport compatible and designed to give you padded protection and insulated warmth, without compromising range of motion thanks to a full neoprene shell with super stretch design. Generous 3cm closed cell foam provides warmth and a boost of buoyancy, and its ergonomic shaping allows a waist or seat harness to fit snugly around your midsection, to keep you feeling locked in.
