Description

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.TechnologyPertex 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.Pertex Y Fuse fabrics use yarns with unique Y shaped filaments. These filaments create a tightly interlocking structure which improves downproof and water beading properties. The interlocking structure of Y Fuse fabrics remains highly stable over extended wash and wear cycles.Super DWR is a water repellent finish that maintains its high performance through extended wash and wear cycles.HyperDRY water-resistant down is treated with a unique fluorocarbon-free treatment that adheres to the down cluster and allows down to retain its superior warmth to weight ratio – even when wet.All down products from Stone Glacier come from an RDS Certified Supplier. We only use down that comes from ducks & geese that were treated ethically.
