The Grumman Goose Down Jacket by Stone Glacier brings the ultimate in packability, warmth, and protection to the backcountry hunter. We set out to design a puffy hunting jacket that truly met our definition of “Ultra-light.” 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 puffy hunting 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 the Grumman Goose Down Jacket an office favorite at Stone Glacier.

Pertex® Quantum uses a tightly woven structure on the Stone Glacier Grumman Goose Down Jacket 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 on the Stone Glacier Grumman Goose Down Jacket 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 allowing the down in this puffy hunting jacket to retain its superior warmth-to-weight ratio - even when wet.
