The Grumman Goose Down Jacket brings the ultimate in packability, warmth, and protection to the backcountry hunter. We set out to design a piece that truly met our definition of Ultralight. The combination of a Pertex Quantum shell with HyperDRY 850+ Fill Power DWR treated down makes this a highly technical insulation piece unlike any other in the hunting industry. Weighing only 11.8 oz. with 5.3 oz. of 90/10 goose down fill, you will be hard pressed to find another down jacket with comparable stats. A well fit hood, reverse coil YKK zippers, and a unique cuff design paired with strategic color blocking for breaking up body symmetry on the mountain have made this piece an office favorite at Stone Glacier.
Surviving a sudden cold snap in the alpine requires a layer that provides maximum insulation without the weight of traditional outdoor apparel. The Stone Glacier Grumman Goose Down Jacket, available at Precision Optics, is a specialized piece of hunting gear engineered for those who prioritize efficiency. This technical hunting clothing utilizes 850+ fill power HyperDRY-treated goose down, offering a superior heat-to-weight ratio that is great for backcountry hiking and hunting where every ounce counts.
