Weighing less than the four Pop Tarts you ate for breakfast, the Grumman Vest shares the same big tech specs as the Grumman Jacket—now in a smaller package. 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.
Pertex® Quantum uses a tightly woven structure to provide a light and soft fabric that allows insulation to fully loft while also being quiet, windproof, lightweight and packable.
Fluorocarbon Free Down Provides increased water resistance to retain loft and help keep you warm in extreme climates.
