Ergodyne - EGO16844 6844 Balaclava Face Mask provides formfitting comfort and protection from cold, wind or snow. This balaclava works as a ski mask to protect everything but your eyes from the elements. A double layer of fabric covers your nose and mouth: a nylon/spandex fabric, outer layer for warmth and a soft, mesh inner layer for breathability. Move the layers below or above your chin depending on your needs. Use mesh layer in warm weather for breathable protection. This feature prevents your glasses from fogging up while working. This stretchy, quick-drying face mask eliminates moisture and cold. Wear this versatile balaclava as a face mask or neck gaiter, or use it as a base layer under a hard hat. Tuck the neck portion into a jacket to seal out cold. This is the perfect winter face mask for those working in construction, freight, mining, oil and gas and more. Wear this face mask during outdoor activities such as hunting, skiing or climbing as well.
