Pros Very inexpensive, versatile, good feature setVery affordable, highly customizable, versatile, lots of featuresWarm for an ultralight bag, simple and versatile design, box baffle construction, waterproof stuff sackWarmth-to-weight ratio, excellent fabric, best bag with a hood, versatileTruly ultralight, packs down well, good zipper
Cons Not as warm as similar quilts, doesn't seal at the bottom very wellLong wait for product to be custom made and shipped, foot box draw cord still leaves a little hole, lots of buttons and strapsA little constricting, small foot box, not the best neck draw cord designTight fit, shallow hood, expensiveNot very warm, tight around shoulders
Bottom Line A functional, versatile quilt well worth the low priceThe warmest quilt in our review also comes at a reasonable priceWith an enclosed foot box and ¾ length zipper, this warm hoodless mummy can also be used quilt styleA very warm and lightweight full mummy with a full zipIf weight and space savings are paramount, the Spark is the tool for the job
