Sequoia Gore Infinium

$896.75 - $985.50


Semi-rectangular 5° F bag with a Gore Infinium shell.

The roomy Western Mountaineering Sequoia Gore Infinium has a highly water-resistant/breathable shell for extreme weather protection. This shell is the most water-resistant, windproof, and breathable fabric suitable for sleeping bags, and 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 full collar completely surrounds your neck and is solidly stuffed with down to provide a protective seal from the heat-robbing bellows effect as you move about inside your bag. The continuous baffles allow you to adjust the down fill to suit the changes in weather, and its two zippers not only allow you to zip to mummy bags but also to unzip the foot so that it can lie out flat. The Sequoia is your best friend when you need elbow room in the most moisture-prone climates.

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