Pros Ultralight, lofty 900FP down, packs small, solid warmth, waterproof stuff sackSpacious dimensions, super comfortable, great loft, lightweight, made in the USASuper lightweight, incredible loft, snag-proof zipper, cozy hoodBest-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 Short half-length zipper that's prone to snagging, narrow leg dimensions, one size "fits" allExpensive, awkward hood, good but not great zipperUncomfortably narrow dimensions, bare-bones design, noisy fabricNarrow leg dimensions, no draft collar, heavier and bulkier than some 3-season optionsBelow average warmth-to-weight ratio, bulky packed size
Bottom Line Premium materials in a bag that's minimally light and smallIf 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 tooExceptional warm and loft along with our favorite hood and zipperAn hourglass bag with premium down and spacious lower dimensions
