Our Innovative Guardian Gear™ Alpine Sleepers combine the convenience of a travel bed with the benefits of a sleeping bag in one versatile pet bed. Oval beds are made of water-repellent polyester filled with soft, warm polyfill and feature a bumper-style edge. Cover fastens around the edge with Velcro® to convert bed into a cozy and snug sleeping bag. Perfect for dogs that like to snuggle. Sleeper conveniently rolls up and packs into the handy drawstring bag for storage and transportation. Temperature range: 30°F/16°C.
