Temperature ratings are intended as a guideline to help you compare products, rather than a guarantee of warmth, since many different factors contribute to your comfort while you sleep. Backpacking bags are typically rated for temperature according to an independent testing protocol-currently International Organization for Standardization (ISO) 23537, though some older items followed European Norm (EN) 13537. Testing is based on a person wearing one base layer and a pair of socks, sleeping on an insulated surface with a minimum R-value of 5.38.

How to choose sleeping bags for backpacking. Do I really need a backpacking-specific bag? These sleeping bags are lighter, pack down smaller and are more efficient at keeping you warm compared to ones for camping. Insulation type and bag shape affect weight the most. Many sleeping bags come in regular, long and short sizes.

Review the bag's size specs for the best fit. Draft-blocking details, a snug-fitting hood, extra zippers and even a stash pocket can add more durability, warmth and function. 15 degrees (F) - ISO. 27 degrees (F) - ISO. 20-denier 100% recycled nylon ripstop.
