How To Buy The Right Sleeping Bag - Cashmere, Wool and Silk directory

Finding the right sleeping bag is essential for a comfortable night�s sleep under canvas and, in extreme weather conditions can prevent serious medical conditions such as frostbite. Modern science used in the manufacture of sleeping bags is very complex, incorporating rigorous testing according to strict guidelines, allowing you to be sure that you will be totally insulated and comfortable, no matter what the weather.

There are myriad of different shapes and sizes of sleeping bag available. The shape of the sleeping bag can be important. If you are travelling somewhere very cold, for example, you may find that a �mummy-shaped� bag provides better insulation, as it follows the contours of your body, ensuring a snug fit. There are mummy-shaped bags specially designed for both the male and the female form so it is important you check the label to select one that�s right for you.

You may prefer a more traditional rectangular sleeping bag, which is usually less insulating than the slimmer models, but comfortable and perfectly adequate for warm climates. You can even find double sleeping bags for those couples that would rather share a bag. They can be surprisingly compact, but you will need to make sure they have strong zips, preferably two-way.

Sleeping bags are made either of synthetic fabric or down (duck down is the most popular variety) and both have their advantages. Synthetic fabrics are obviously very practical, in that they are lightweight and easy to wash, as well as waterproof. Some are made of �hollowfibre� fabric, which is suitable for a warm climate. Microfibre sleeping bags are preferable for added warmth as they are much more insulating. Some microfibre and hollowfibre bags are hypoallergenic, reducing the risk of allergy aggravation, and they are cheaper than down sleeping bags.

Down sleeping bags have the best compression ratio, meaning that they fold down to the smallest size in the carrier, and are also lighter than synthetic bags, whilst providing the most comfortable and effective insulation. They are slightly less reliable in terms of cleaning practicality. However you can always purchase a cotton or polycotton lining, which is a simple and hygienic solution. These inner linings can also be used as a summer bag in very warm temperatures, and come in a variety of shapes and sizes.

The cost of your sleeping bag will vary according to the quality of the fabric and the added details, such as added neck insulation, two way zips for more secure fastening, or even glow in the dark zips, which are very useful. It is worth checking that the zips are attached to anti-snagging tape, which makes for a longer life span. Some bags are only suitable for one season according to their warmth rating or �tog�. However there are others which are scientifically produced to cater for two, three or even four seasons, and capable of keeping you warm and comfortable in a number of different temperature ranges. These are certainly a very good investment and also tend to be the most technically advanced type of bag.

The weight and size of your sleeping bag is also worth consideration. If you are trekking for long periods of time, then the least bulky and lightest bag is worth the extra cost. -- iS
