Coleman Sleeping BagsColeman's range of sleeping bags have been tested in the independent Laboratories of the School of Physics and Materials Engineering at Monash University in Melbourne. Dr Don Hutton, an Honorary Research Fellow and a keen bushwalker and camper, conducted the tests by inserting a centrally heated 'mannequin' into the sleeping bag and maintaining a constant power input. The temperature changes are recorded by electronic heat probes and the information fed into a computer over a extended time period, providing the data to rate the bags scientifically. All of the Coleman sleeping bags have limited lifetime zip warranty's twin zips to join two bags, full zip draft guards and 4-way compression stuff sacs. Why are Coleman bags the best? - Unique and innovative comfort design features
- The best materials in an affordable bag
