Issued by the U.S. military for Arctic and extreme cold operations, this vintage U.S. GI face mask is designed to protect the wearer from bitter wind, snow, and sub-zero temperatures. Constructed from a durable water-resistant nylon shell with a quilted insulation layer, it provides full facial coverage including a built-in neck flap. Perforations at the mouth and nose help with breathability while limiting frost buildup.
 
This model features adjustable canvas straps for a snug fit and it intended to be universal size. However, it tends to run small—ideal for medium to smaller head sizes. Those with larger head sizes may find it too tight or not wearable.
