Antelope GWS – Gore Infinium™ 3-Season Alpine Sleeping Bag

When your adventures take you high into the Sierra Nevada, Rockies, or other alpine ranges, the Antelope GWS offers maximum protection in a true three-season design. Built for mountaineers, alpine climbers, and serious backpackers, this bag combines lightweight packability with the weather resistance and warmth needed for early spring through late fall expeditions.

With 26 oz. of premium 850+ fill power ethically sourced goose down, the Antelope GWS delivers 7 inches of loft and a 5°F (-15°C) temperature rating—keeping you warm when conditions turn cold at altitude. The 62″ shoulder girth ensures comfort without sacrificing thermal efficiency, while the 3D down-filled collar, full-length draft tube, and well-shaped hood lock in heat.

Crafted from Gore Infinium™ 830 fabric—the lightest, most compressible Infinium available—this bag offers exceptional water resistance, windproof protection, and breathability in a laminated shell designed specifically for sleeping bags. Both the collar and draft tube are fully wrapped in Infinium™, creating an impenetrable seal against cold air and spindrift.

At just 2 lbs 13 oz (1,280 g), the Antelope GWS is one of the most substantial and weather-ready three-season alpine bags available. Also offered in a 5’6″ length for compact climbers and backpackers.
