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.


PRODUCT TECHNOLOGY

Pertex® Quantum uses a tightly woven structure 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 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 that allows down to retain its superior warmth to weight ratio - even when wet.


Responsible Down Standard (RDS)

All down products from Stone Glacier come from an RDS Certified Supplier. We only use down that comes from ducks & geese that were treated ethically.
