Down fill weighs less than synthetic and retains heat better, but usually costs more. Down must be kept dry; a soaked down sleeping bag may provide even less insulation than no sleeping bag at all, leading to [[hypothermia]]. Newer, more technically advanced sleeping bags often have water-resistant shells and can be used in damper conditions. It is also recommended to keep a sleeping bag in a larger sack (storage sack) as opposed to the small traveling sack (compression bag) during long periods of storage. However, many regular backpackers and hikers agree that hanging a sleeping bag, taking care to move the position of the bag on the hanger at intervals so as to not create a "dead spot" (a spot where the fill has been crushed so that it is no longer useful), is the best method of storing a bag for long durations. | Down fill weighs less than synthetic and retains heat better, but usually costs more.

Other materials, notably | Other materials, notably cotton and [[wool]], have also been used for sleeping bags. Wool repels water nicely and also resists compression, but it weighs much more than any alternative. Cotton suffers from high water retention and significant weight, but its low cost makes it an attractive option for uses like stationary camping where these drawbacks are of little consequence. | ||
