Description 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.
