Description

***Stone Glacier products are designed with an athletic fit to provide its users with the highest performance possible in the field. Please use the sizing tab to help guide you to the correctly sized garment***

The Stone Glacier Grumman Down Jacket delivers premium warmth, weather resistance, and exceptional packability in an ultralight insulation layer made for demanding backcountry hunts. Insulated with 850+ fill power HyperDRY® DWR-treated goose down and protected by a wind-resistant 15D Pertex® Quantum shell, it provides an outstanding warmth-to-weight ratio without adding unnecessary bulk. An updated micro-ripstop face fabric with a matte finish offers improved durability and quieter performance in the field, while subtle fit refinements enhance comfort and layering. The articulated hood, streamlined internal cuffs, elastic hem, and reverse-coil YKK® zippers help seal in warmth, and the internal pocket doubles as a stuff sack for compact storage when it's time to keep moving.
