Descente Allterain definitely knows its way around a warm down jacket so why not build the perfect winter boot with same approach? They have done exactly that with their latest collaboration with Suicoke. Their Waterproof Down Boots feature an upper that's made at Descente's Mizusawa factory with the same technology found in their Mizusawa Down jackets. The heat-welded quilting creates a waterproof shield and optimal down placement to keep your feet extra warm. It's also got a Cordura nylon outer shell for durability and the lining uses Descente's HEAT NAVI material for an extra layer of warmth.
