Pros Light, packs down really small, the best pad attachment systemLightweight, warm, seals well for a quiltTruly ultralight, packs down well, good zipperWarm for an ultralight bag, simple and versatile design, box baffle construction, waterproof stuff sackSuper lightweight, water-resistant down, nice fabric
Cons Doesn’t wrap all the way around, less versatile than other quilts, enclosure systems require lots of fiddlingHard to vent, pad attachment system not intuitiveNot very warm, tight around shouldersA little constricting, small foot box, not the best neck draw cord designCould use a second attachment strap, snap sometimes comes undone
Bottom Line A warm, lightweight, small packing quilt that takes more work, but attaches more securely to a pad than any other quiltA great option for those looking for a good warmth to weight ratio in a quiltIf weight and space savings are paramount, the Spark is the tool for the jobWith an enclosed foot box and ¾ length zipper, this warm hoodless mummy can also be used quilt styleThis quilt maintains comfort while still being the lightest quilt in the review
