“What's that tongue-looking thingy?” you ask. It's not a blanket, but actually an integrated comforter. Put your hands in its pockets to keep it wrapped around you. There's no zipper or drawstring, so movement is unrestricted. Plus, there's an integrated sleeve to slip a mattress underneath. Unfortunately, the insulation feels pretty thin from the small of your back to your shoulders. While this unique take on the mummy bag is warm and lightweight, some might be discouraged by its price.

Pros: Pioneering design provides unrestricted movement, Foot vent enables you to slip your toes out with ease if you're getting too warm, More than one attachment option on storage bag

Cons: No storage pockets, A bit of a financial investment
