You only need to have spent one night in a sleeping bag to have invented the Crash Sack from REI’s Evrgrn collection. We’ve all thought we’d like to be able to slip our arms in and out or pop a foot out to cool off or walk around without getting out of the bag. Thankfully, REI has finally created that dream bag. Of course, a pre-requisite for really enjoying it, is that you can’t care what people think of you essentially wearing an outdoor Snuggie. It comes in three sizes, has interior pockets (now we’re talking) and synthetic fill rated to 45 degrees. You can get it right now for $119, but if you insist on wearing it for those late night nature calls trips out of the tent, you won’t be allowed back in.
