It is when one has to spend the night out in the open that one wishes for the cozy bed to sleep on. Blankets, bed sheets and pillows have been used to make it as close to a bed as possible. But not really. These efforts gradually transformed into sleeping bags. Resembling a blanket with a zipper, the sleeping bag is intended to provide insulation, warmth and comforts as a bed. Most important of all, the sleeping bag is something one can simply carry it along while traveling in a backpack. This comes in particularly useful when one is camping.
The sleeping bag protects you from the wind and keeps precipitation out to a great extent. You are protected from the outside. The insulating materials that are used in sleeping bags are either synthetic such as PrimaLoft. Or it could be down fill. Sometimes wool and cotton too are used to make sleeping bags. The synthetic sleeping bags are better insulators and water is not readily absorbed. It can also be folded like a blanket. The down fill bag is the better one for retaining heat. It can be compressed too. But the synthetic sleeping bags are cheaper.
Sleeping bags are available in two shapes namely the rectangular sleeping bag and the mummy shaped ones. The rectangular sleeping bags are bigger resembling a folded blanket that is zipped. It has straps or cords for securing the bag once it is folded. The mummy shaped bag has a broad and open portion at the shoulder tapering down as it comes to the leg side. It is smaller but has a better heat retention capacity. It cannot be folded but has to be rolled and stuffed into a sack for it to be carried easily. Sleeping bags are found with camping equipment dealers. A light sleeping bag that is comfortable is the marmot atom bag.
The down bags do not fare as much as the synthetic bags under wet conditions. The down bags are lighter. But the synthetic bags are cheaper. You will have to choose on the basis of the conditions you require your sleeping bag to be used. But rest assured that you will have a pleasant sleep. Sleeping bags keep you warm whenever you are out in the cold. So, when you go outdoors, always bring the best sleeping bags with you.
