Western Mountaineering UltraLite Sleeping Bag: 20F Down

The Western Mountaineering UltraLite Sleeping Bag lives up to its name by keeping our backpacks light while still packing in a hefty dose of premium 850-fill down for those chilly nights. A soft taffeta lining caresses trail-weary skin and, thanks to the ExtremeLite shell's breathability, the climate inside of the bag stays comfortable on balmier nights.
