Sleeping bags
- Rectangular
The rectangular sleeping bag is probably the most common, and are popular for light use. They are not suitable for backpacking because they provide the least amount of warmth and the most amount of weight. As the name implies, they are rectangle-shaped. While this makes them comfortable and roomy, the wide opening near the top is a major source of heat loss. Unlike a mummy bag it does not have a hood that can be drawn around the head to retain heat.
- Mummy Bag
The mummy bag is shaped like a sarcophagus. It is narrow at the feet (but tall there to allow just enough room for the feet), tapers at the waist, widens again at the shoulders, and then tapers down near the head. The top is very much like the hood of a winter coat, complete with drawstrings to close up the gap and keep heat in. Because they conform so well to the human shape, there is very little wasted space inside. This is good because your body has to heat all that space, and because the extra insulation and material thusly removed does not have to be carried (meaning it's lighter).
- Barrel Bag
The barrel bag is a modified mummy bag. It is roomier than the mummy bag and provides almost the same warmth at the cost of additional weight.
Sleeping Pads
Sleeping pads can perform two main functions:
- Provide cushioning
- Provide insulation between the sleeper and the ground.
- Air mattresses
Air mattresses are inflatable cushions that can provide a lot of comfort when it comes to sleeping on the ground. Unfortunately, they are not very warm as they provide next to no insulation beneath the sleeper. This may not be an issue, though it is well worth knowing.
- Open-cell foam pads
Open-cell foam is a type of foam padding that is sometimes found in furniture cushions or even in regular mattresses. It is lightweight - though somewhat bulky. Its chief disadvantage is that it soaks up water like a sponge.
- Closed-cell foam pads
Closed-cell foam makes the ideal sleeping pad. The closed cells do not soak up water. They are lightweight, comfortable, and compact. Often they are only half an inch (12 mm) thick, so they can be rolled into a small tube and strapped to a backpack. They also serve as an excellent thermal barrier between the sleeper and the ground.
