15 degrees of windproof, water-resistant boundary-pushing; narrow cut

The Western Mountaineering Apache Gore Infinium is built with attitude! This windproof, highly water-resistant and breathable 15° F bag won't take no for an answer as it pushes the bounds of what a late-summer/early-fall bag can do. A full 3-dimensionally sewn down-filled collar seals in heat when the weather takes a turn for the worse. The slim, heat-efficient cut lets you warm up the bag quickly and makes for a light, compressible package. 19 oz. of high lofting down pumps up a durable 6" of loft. The Apache Gore Inifinium is a very efficient package that is built like a pint-sized winter bag. At a total weight of around 2 lbs 6 oz, you'll be amazed just how much cold these bags will tame.

Like all of Western Mountaineering's bags, the Apache 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.
