Pros Super lightweight, water-resistant down, nice fabric.Highest scoring ultralight sleeping bag, best features, and most versatileVery affordable, highly customizable, versatile, lots of featuresWarmth-to-weight ratio, excellent fabric, best bag with a hood, versatileWarm for an ultralight bag, simple and versatile design, box baffle construction, waterproof stuff sack
Cons Could use a second attachment strap, snap sometimes comes undone.Not as warm as others (in the version we tested), neck draw cords loosen over timeLong wait for product to be custom made and shipped, foot box draw cord still leaves a little hole, lots of buttons and strapsTight fit, shallow hood, expensiveA little constricting, small foot box, not the best neck draw cord design
Bottom Line This quilt maintains comfort while still being the lightest quilt in the review.The best performing set of features that allow for the most versatile usage.The warmest quilt in our review also comes at a reasonable price.A very warm and lightweight full mummy with a full zip.With an enclosed foot box and ¾ length zipper, this warm hoodless mummy can also be used quilt style.
