[$100+] One part sleeping bag and one part 1950s Hollywood space suit, Selk’Bag Sleep-Wear Systems are on the cutting edge of unusual yet effective sleeping bags. While we can’t say we’d be thrilled to take a hike in one, we have to admit they are damn comfy for sleeping. Selk’Bags range in style and price from the Lite version (rated to 45 degrees) to the full version (rated to 34 degrees, but with some added heft). While they’re not hardcore enough to sustain a full on arctic adventure, Selk’Bags offer plenty of comfort for your average camping trip without the claustrophobia of your standard sleeping bag.
