The N-Ferno 6844 Dual-Layer Balaclava Face Mask provides form-fitting comfort and multi-functional protection from extreme weather conditions such as the cold, wind and snow. This balaclava works as a ski mask or a staple on the job to keep you warm and dry so you can focus on the task at hand. A double layer of fabric covers the nose and mouth so you can pull the nylon, spandex outer layer down below your chin to reveal the soft, breathable, mesh bottom layer. This is also convenient for preventing your safety glasses or sunglasses from fogging up. Cover all but your eyes (since you'll probably need those) or wear as an open face mask or neck gaiter. This multipurpose balaclava can be worn comfortably under your hard hat or ski helmet. Designed with lightweight, quick-drying and high stretch material to offer maximum protection against the elements in harsh conditions.
