PrimaLoft® Silver and Gold Insulation gives maximum warmth and an additional Octa® Loft breathable insulation lining next to skin manages moisture and makes for an easy on/off. Too add to the ruggedness, a double layer of premium goat leather reinforcements enhance durability. An elasticated wrist strap provides a precision fit and the pull to open/pull to close gauntlet ensures severe weather is sealed out.
