The Stone Glacier Men's Grumman Down Jacket delivers exceptional packability, warmth, and protection for the backcountry hunter in a truly ultralight package. Built with a Pertex Quantum shell and insulated with HyperDRY 850+ Fill Power DWR-treated goose down, it remains one of the lightest and most technically advanced down hunting jackets available. This updated version features a refined face fabric using a dull yarn and a micro-ripstop construction for improved durability and a quieter, matte finish in the field. Pocket depth has been increased by 2 for enhanced comfort and usability, and a built-in containment pocket allows the jacket to compress into itself for easy packability. Subtle fit adjustments improve overall comfort and layering performance, while a well-fitting hood, reverse-coil YKK zippers, and a unique cuff design complete this proven insulation piece.
