Specifically constructed to provide superior warmth where women need it most, the Women's Xenon is the lightweight bag you'll fall in love with. Made from high-quality, 850+ fill goose down piled extra deep in areas where the female body loses heat, this bag is also super light and compressible, thanks to the Pertex Microlight shell and lining fabric. Durable enough to resist rips and punctures, and rated down to 15°F, you can't beat this bag for hiking, mountaineering and backpacking.
