    Expert Review

    At 1 lb 9.7 oz with a 15F rating, this is a great compromise of weight and warmth for colder nights in the mountains. This is one of the few items on this list that I haven't personally tested. I use the Patagonia Hybrid sleeping bag which has since been discontinued. But if I were getting a new sleeping bag, this is what I'd get!
