Weighing less than the four Pop Tarts you ate for breakfast, the Stone Glacier Grumman Down Vest shares the same big tech specs as the Grumman Down Jacket. Inside, find 850+ fill treated goose down. Outside, find a 15 denier Pertex® Quantum shell. Use it as an active insulation piece or, when temps plummet and you need to stay behind the glass, pair it with the Grumman jacket for the ultimate warmth combo. FEATURES & SPECS Weight - 8.8 oz.
