In autumn and spring, a down vest is perfect! Our ultralight down vest has 90% protective soft down and 10% feathers that create extra warmth. Small air pockets are created by the down, which conserves heat by trapping and holding the warm air. Scandinavian Explorer only uses down that is certified. (By-product of food production.) Lined with 100% nylon. Large selection of sizes. Designed by Scandinavian Explorer in Norway.
