Originally bought this thinking that it could work as a substitute for a sleeping bag for summer camping but I believe that it is too light for that. If you were camping in the summer on a tropical island or in the desert it might work. That said, it is still the most comfortable lightweight couch or recliner blankie (for shorties like me). So, I suspect that it will actually work well as a car or air travel blanket. Packs down small in its own stuff sack.
