Recent Sleeping Bag News

Loft and fill type are other important points of comparison.  Loft refers to the thickness of a sleeping bag; it is an important factor when considering warmth.  The fill used in sleeping bags has many qualities to be considered, including weight, compactness, durability, and warmth when wet.  Common fill types include goose down, Hyperloft, PrimaLoft, and Hyperloft Lite.  Goose down, the sleeping bag fill standard, is lightweight and an efficient insulator.  It compresses well and lofts quickly when shaken.  It can, however, lose insulation value if it gets wet, and it also dries slowly.  Synthetic fills don't lose insulating value if they get wet, and they dry quickly.  Sleeping bags with synthetic fill are usually cheaper than down-filled bags, but they tend to be heavier and larger than down-filled bags.

Shape is also an important consideration when choosing a sleeping bag, and there are several specific shapes to choose from.  A mummy bag narrows at the feet, flares at the shoulders, and tapers to a hood.  It is designed to reduce weight and maximize heat retention with its close, narrow fit, but mummy bags can feel somewhat confining.  A barrel bag is a bit bulkier than a mummy bag.  It is slightly tapered and has an oval foot section.  A rectangular bag is most practical for warm weather.  It is the roomiest type of sleeping bag, and two rectangular bags can easily be zipped together to form a larger bag.  While a rectangular sleeping bag is the least expensive choice, it may not be the most practical for a hiker, because it is bulky and does not provide much insulation.  Choose an extra-long sleeping bag if you are over six feet tall.  And, if you are a woman, you might want a bag that is designed for women.  These bags are shorter, with a wider hip area and narrower shoulder size.
