Stone Glacier Grumman Down Pants

Cold weather can slow you down fast, especially when you stop moving. The Grumman Goose Down Pant gives you serious warmth in an ultralight, packable layer that is easy to carry and even easier to deploy when conditions turn harsh. Designed for backcountry use, it works over your pants during static cold conditions or underneath rain pants when the weather is extremely cold and wet.

Built to reduce weight and maximize packability, this down insulated pant is made for hunters, hikers, and mountain travelers who want real warmth without giving up space in their pack. The 15D Pertex® Quantum shell and 850+ fill power HyperDRY™ DWR-treated down create an outstanding warmth-to-weight ratio, while the full-length side zips open completely at the waist hem and cuff for quick on and off in the field. Patterned shell textiles add durability in high-wear areas, and the slim waistline layers comfortably under a pack belt. When the temperature drops and glassing, camping, or extended breaks demand more insulation, the Grumman Goose Down Pant is the layer you’ll be glad you packed.
