Pros Very affordable, highly customizable, versatile, lots of featuresHighest scoring ultralight sleeping bag, best features, and most versatileWarmth-to-weight ratio, excellent fabric, best bag with a hood, versatileWarm for an ultralight bag, simple and versatile design, box baffle construction, waterproof stuff sackSuper simple and light, highest quality down, spacious and comfortable
Cons Long wait for product to be custom made and shipped, foot box draw cord still leaves a little hole, lots of buttons and strapsNot as warm as others (in the version we tested), neck draw cords loosen over timeTight fit, shallow hood, expensiveA little constricting, small foot box, not the best neck draw cord designNo 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 bags
Bottom Line The warmest quilt in our review also comes at a reasonable priceThe best performing set of features that allow for the most versatile usageA very warm and lightweight full mummy with a full zipWith an enclosed foot box and ¾ length zipper, this warm hoodless mummy can also be used quilt styleThe 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 you
