This is a full-cover balaclava that effectively protects against wind and cold. The upper part is made of breathable lycra, while the face is shielded by windproof neoprene. The warm exhaled air from both the nose and mouth is directed downward to avoid fogging on visors and glasses. Stretchy panels and extra protection over shoulders and neck makes this a super comfy face mask. Fits perfectly with all our helmets.
