Pros Spacious dimensions, super comfortable, great loft, lightweight, made in the USASuper lightweight, incredible loft, snag-proof zipper, cozy hoodBest-in-class warmth, legit draft collar, light weight, exceptional loftBest-in-class zipper, best-in-class hood, awesome loft, great warmth-to-weight ratioSpacious hourglass shape, innovative venting "gills", waterproof footbox, sturdy compression sack
Cons Expensive, awkward hood, good but not great zipperUncomfortably narrow dimensions, bare-bones design, noisy fabricReally pricey, kind of bulky, awkward hood closureNarrow leg dimensions, no draft collar, heavier and bulkier than some 3-season optionsBelow average warmth-to-weight ratio, bulky packed size
Bottom Line If we could only have one bag for the rest of our lives, this would be itThe ideal bag when you need the warmth, but ounces matter tooThe best bag for the coldest shoulder season nightsExceptional warm and loft along with our favorite hood and zipperAn hourglass bag with premium down and spacious lower dimensions
