The Portwest HA18 Helmet Liner Cap is a low-bulk layer of warmth for wear under a safety helmet. It sits close to the head, so it adds warmth without crowding the space inside your helmet.
The stretchy polyester and elastane fabric moves with you. It also draws moisture away from the skin, helping you stay cool and dry while you work.
