Summer camping in the Utahs northern mountains calls for a cozy sleeping bag such as The North Face Wasatch Bx Sleeping Bag. The North Face stuffed this 40-degree sleeping bag with Heatshield Optimal Technology HOT SL, a lightweight, durable synthetic insulation that traps air. Your body heat warms that air to help you stay toasty after sunset when temps drop. Overlapping shingle construction eliminates cold spots, and a hood zipper lets you cover your face against a cold draft or vent when the night is balmier than you expected. Stash your headlamp in the shoulder-level zip pocket, and get comfy.
