Wide-cut 5° F mummy with a Gore Infinium shell.

　　When places like the Cascades or Rocky Mountains are your stomping grounds and you need a light and warm bag to push the 3-season boundaries, leave nothing to chance with the Western Mountaineering Antelope Gore Infinium. It features a Gore Infinium shell: the most water-resistant, windproof, and breathable fabric suitable for sleeping bags for extreme weather protection. The down-filled collar and draft tube are also made with Gore Infinium to prevent moisture absorption and keep the wind out of your bag. The Antelope's roomy 62" shoulder girth allows for comfort and the 7" loft from 26 ounces of high-lofting 850+ down provides warmth to 5° F. The neck and zipper of this bag are sealed with a full 3-dimensional down-filled Super Collar and a robust draft tube. This 5° F sleeping bag takes over in early spring and lasts till late fall, and is the most substantial of Western's 3-season bags.

　　Like all of Western Mountaineering's bags, the Antelope is made by hand in San Jose, California. Their down is sourced from free-range mother geese who are never live-plucked or force-fed.

　　The GORE-TEX INFINIUM™ WINDSTOPPER® series enhances quality and performance, combining versatile aspects of support and comfort without the need for total waterproof protection. Durable water resistance combined with increased breathability, better packability, and optimized lightweight elements are the defining features of this technology. GORE-TEX INFINIUM™ WINDSTOPPER® is totally windproof and provides highly water-resistant protection for unstoppable performance.
