The Stone Glacier Grumman Down Pant is a lightweight, highly packable insulation layer built for cold, demanding backcountry hunts. Insulated with HyperDRY® 850+ fill power goose down and protected by a Pertex® Quantum shell, these pants deliver an exceptional warmth-to-weight ratio when conditions turn harsh. A true full-length side-zip design opens completely at the waist hem and cuff, allowing for fast, frustration-free layering over boots and outerwear. Updated with a durable micro-ripstop face fabric using a dull yarn, the Grumman Pant features a quieter, matte finish for improved field performance. A built-in containment pocket allows the pant to stuff into itself for easy packability, while refined fit adjustments enhance comfort and mobility. Perfect for long glassing sessions or extended stops in cold terrain, the Grumman Down Pant is a game-changing piece you'll never want to leave behind. FEATURES & SPECS Weight - 13.6 oz.
