The way to select Optimal Sleeping Bag

Introduction 
Slipping in to a warm and comfortable sleeping bag is among the greatest pleasures of countryside camping. To keep the night chill from increasing, you must pick a sleeping bag of your right temperature rating, shape and insulation. Other factors to consider may include features, cost and roominess that add to convenience and comfort. 
Temperature rating 
This is determined by the season while you are probably to work with the bag- summer, winter or as soon as the temperatures are moderate. Generally the bag’s name gives an idea about its rating, as an illustration Marmot Plasma 15 bag is one rated to your temperature of 15F. If you happen to like camping during winter, go with a bag rated at below 0F while a bag suited for summer camping is rated 35F and better. Many people opt for the 3-season bag by using a temperature rating of 10F to 35F as it is appropriate for varying seasons.

Type of insulation 
Nearly all sleeping bags come in three types of insulation — the, down and synthetic water-repellent down. Down bags are filled with duck and goose feathers. These are light, compressible, breathable and durable. However they are relatively expensive and can be allergic to users. Synthetic insulation is fairly cheaper, quick-drying, insulates regardless if wet, and contains considerable durability. Synthetic insulation is not compressible and thus occupies larger room when packaged, however. The liquid-resistant down insulation maintains insulation even if put on wet ground. 
Shape and loft 
Loft can be a key issue in determining a sleeping bag’s warmth. It means the puffiness or perhaps the thickness in the bag (a measure of the outer diameter of your bag). Just in case two bags have the same shape, type and features of fill, the one that carries a higher loft is warmer. Sleeping bags are available in three shapes- rectangular, semi and mummy-rectangular. Mummy-shaped bags are tapered at one end in order to concentrate more warmth to the body. Rectangular sleeping bags offer greater room for the user to advance their feet. The semi-rectangular bags combine the main advantages of another two plus they are more preferable. 
Other bag features 
It is also good to confirm bags for zipper compatibility. In the event that two bags should be zipped together you need to choose a bag with a “right-hand” zipper and the other one with a “left-hand” zipper. Other features it is possible to try to find add the availability of a built-in hood into which you can stuff clothes to form a pillow. You might also search for a draft tube that operates on the primary zipper to boost insulation. It is best to look for the inclusion of a stash pocket into which you could put a watch, glasses, phone or other small gadgets. 
Conclusion 
Deciding on a a sleeping bag is largely influenced by the season in which it is supposed to be applied. , type of insulation, storage room as well as the shape can also be critical factors that you should consider.Cost and weight Features such as a built in presence and hood of the stash bag can add to your comfort and convenience.
