The Grumman Goose Down Jacket brings the ultimate in packability, warmth, and protection. 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. Weighing only 11.8 oz. with 5.3 oz. of 90/10 goose down fill, you will be hard pressed to find another down hunting jacket with comparable stats. A well fit hood, reverse coil YKK zippers, and a unique cuff design. 15 Denier Pertex® Quantum Shell 850+ Fill Power Goose Down HyperDRY™ DWR Treated Down 100% Traceable RDS Certified Down Articulated Hood Weight - 11.8 oz.
