The Poler Nap Sack is pretty much a wearable sleeping bag. Or maybe a really oversized sleep-able puffy jacket. Either way, it's warm, cozy, and functional. The Nap Sack features zippered arm holes and a cinchable open bottom so you can stick your feet out the bottom and hang out around the campfire/living room/wherever—and then close it up and crash without ever leaving the comfort and warmth of your bag.
