The Gauntlet Mitten System was designed for the harshest conditions. It features our Gauntlet Mittens, made of KarbonXtreme. The system includes both full fingered knit liner gloves and 1/2 fingered knit liner gloves of 100% wool. This allows maximum dry warmth and layer changes. For full- day stand sits at subzero temps we recommend a liner change during the day.
