Good sleeping bag can really do or hurt whole camping journey. It really matters to get good rest outside, especially if the days are full of fun activities. The right sleeping bag keeps the body warm and comfortable during the whole night and now there are quite a lot of options to fit well to the needs of any camper or area.
Usually one finds two main kinds of sleeping bag. Backpacking bags weigh less and pack to smaller size, so they work more for hikers. Bags for car camping or campgrounds are bigger, broader and usually much more cheap.
How to Choose a Sleeping Bag
That clear benefit one enjoys, when one does not care to carry heavy load on the back.
The ratings about temperatures are important. Bags for two seasons usually work for temperatures between 0°C and 5°C. They work well from late spring until early autumn in quite a lot of mild regions. They find a balanced spot between warmth and weight, what makes them handy for those, that travel in cold, but not freezing weather.
Some models cover several temperature zones, from 0°F until 40°F, so that the chioce depends on your own need.
Form is another spot, that one must consider. Mummy bags are slim and work to keep heat inside. Rectangular models give more space and feel like sleeping in a normal bed.
Some campers, that are big or long, hardly fit in standard sizes. A bag can seem comfortable on the label, but the hood too tighten, when one really lies inside it.
For instance, the Black Sierra Gear +40°F Camping sleeping bag measures 33 inches broad and 75 inches long. It carries 3 pounds of hollow fiber fill, strong outer shell and soft inner lining in roomy rectangular form. The Ozark Way Happy Camper 50F offers a similar rectangular option with near measurements.
Such budget friendly bags work great for spring and summer camping, although the temperature ratings sometimes a bit stretch the reality.
For pairs there are double sleeping bag options. The Nuba Stratified Double is a grate bag meant for two people, that want a home bed outside. It works as a modular sleep setup, what sounds quite attractive.
Sleep quilts deserve attention also. They pack just as well as usual bags. Some campers find them totally amazing.
Bags with cotton cover also have followers, because the inside feels more comfortable and less cold while getting in, when the material breathes and absorbs moisture like home sheets. The tech fabrics, that usually appear in backpacking bags, can seem freezing to touch and do not breathe as well.
If you plan to camp in cold weather, do not lie too near the campfire, thinking, that it will solve everything. More smart is tochoose a better sleeping bag or improve the sleeping pad.
