Weighing less than the four Pop Tarts you ate for breakfast, the Stone Glacier Grumman Vest shares the same big tech specs as the —now in a smaller package. Inside, you'll find 850 fill-treated goose down. Outside, this ultra-light down vest you'll 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 on this ultra-light down vest uses a tightly woven structure providing 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 applied to this ultra-light down vest. Super DWR helps it maintain 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 allowing the down to retain its superior warmth-to-weight ratio - even when wet.
