The newest tech in sleeping bags is body mapping, and Sierra Designs is leading the way. The idea is simple: Put more insulation where your body is more sensitive to cold, and less elsewhere. You get a lighter sleeping bag that stuffs smaller, but you're not cutting corners on warmth. And while Sierra Designs started this concept this spring with the pyro 15, they're already improving on the idea with the super smart Pyro Maniac 15/30.
