Pros Super simple and light, highest quality down, spacious and comfortableHighest scoring ultralight sleeping bag, best features, and most versatileSuper lightweight, water-resistant down, nice fabricRoomy hood fits a camping pillow, sleeping pad slot, zipperless system, comforter design, convenient foot ventLightweight, warm, seals well for a quilt
Cons No zipper, hard to tell the difference between variable fill zones, must be paired with warm jacket, feet can get hot in warmer weather, not as versatile as other ultralight bagsNot as warm as others (in the version we tested), neck draw cords loosen over timeCould use a second attachment strap, snap sometimes comes undoneNot the best for side sleepers, warmth-to-weight ratio could be betterHard to vent, pad attachment system not intuitive
Bottom Line The only mummy bag that uses more down fill in the foot box and less around the torso, to take advantage of the clothing you have with youThe best performing set of features that allow for the most versatile usageThis quilt maintains comfort while still being the lightest quilt in the reviewCan't decide between a sleeping bag or a quilt? This model hikes right down the middleA great option for those looking for a good warmth to weight ratio in a quilt
