Tension Brick 400 Sleeping Bag: 41F Down

You could smack your head with a brick every night you're camping to make sure you stay asleep, or you could backpack with Yeti's Tension Brick 400 Sleeping Bag. It weighs a lot less and is more compressible than real bricks; for another thing, and you won't have to go to the doctor when you get back to check for permanent damage. Its temperature range is ideal for summer evenings, late spring trips, and early fall adventures.

Yeti insulated the Tension Brick with light, lofty, compressible, and warm Crystal Down insulation so you can take the bag wherever you roam. The hood is detachable, and you can attach it on either side in case one side gets a bit of water (or worse) on it. The two-way, full-length zipper allows ample ventilation and transforms the bag into a blanket for optimal cuddling with a fellow camper and/or bear.
