Western Mountaineering set out to make the lightest possible fully featured bag. They called it the Summerlite, and it's perfect for AT thru-hikers and bike touring.

• Continuous-baffle construction keeps down evenly distributed throughout the bag
• Lightweight nylon ripstop shell keeps the weight at a minimum
• 850+ fill is the highest-quality goose down for the best insulation available
• DWR shell fabric treatment protects the down from spills and condensation
• No need to skimp: this bag has a full-length zipper and an insulated draft tube
• Two-way zipper allows more options for temperature regulation
• Stiffening tape along the zippers ensures snag-free use
• Water-resistant stuff sack with handle loop for use on the trail
• Storage sack to keep your bag lofted when you get back home
