There are a variety of sleeping bags on the market. The type that you choose should be dependent on the climate where it will be used and your own personal preferences. Purchasing a sleeping bag is similar to buying a new mattress – you should consider the size, shape, type of fabric, and amount of free space provided. As for the influence of the weather, if it is dry and warm you may only need a fleece bag or “bed-roll”, whereas colder climates dictate the need for a warm, insulated bag.
There are generally two different shapes to choose from, and each comes with different styles and features. The most popular bag, and also the one that has been used for several years, is rectangular. Due to its shape and the way is made, it can also be used as a comforter. As a sleeping bag it provides a roomy and comfortable space to rest in. And you can sometimes put two of these types of bags together and make a larger bag that can be comfortable and used by more than one person.
Another type of sleeping bag that is gaining in popularity with its more modern style, is the mummy style one. These bags are especially good when it comes to keeping warm, because they fit snugly around you as you sleep. And because of the way it is made, it actually uses less material than its counterparts. The mummy sleeping bag is ideal for use in cold weather, and is lightweight making it easy to carry around while backpacking or going on camping trips.
Most sleeping bags come in one of three sizes. So choose whichever size that will provide the most comfort. The first size, is the child or junior size, which is perfect for smaller children. The next size up, is standard. Most adults fit in it comfortably, but it can also be used for children if you want a sleeping bag that will last longer. The third size is extra long which is generally used by individuals that are six feet or taller. But it can also be used by anyone who likes the idea of having a little extra room in their sleeping bag.
Traditionally, the warmth of a sleeping bag depended on prime goose down which is often used as insulation. Modern designs, however, rely on synthetic fibers which provide greater durability, less weight and easier washing than goose down. Goose down is still used to insulate top of the line mountaineering bags that are used by professionals to keep them warm in extremely cold and dry conditions. These sleeping bags can be prohibitively expensive and certainly beyond the scope of what a family camping trip might call for. Synthetic materials are perfect for most people.
