Seattle-based designer Andy Storms is extending that pleasure to man's best friend with the BarkerBag. It's an insulated sleeping bag for dogs that connects to mummy-style sleeping bags via the zipper, allowing both dog and master to share body heat while sleeping in the great outdoors.

Designed in a teardrop shape, the BarkerBag zips to either side of a standard mummy-style sleeping bag. It can also be attached between two sleeping bags that already mate together. A reinforced cinchable collar keeps the furry friend secure inside the bag and prevents not only heat escaping, but the dog from wandering off by themselves into the night.
