Rectangular sleeping bags are the original and most common shape you'll see on the market. These are simple but effective designs and continue to dominate the market for recreational camping and slumber parties alike. While originally being just two blankets zipped together, over the years the technology has allowed manufacturers t fill them with synthetic material creating better heat retention than the old styles. Some are filled with synthetic fiber, wool, cotton or down however if you're allergic to down, this may not be an option for you. There are many debated as to which one keeps you warmer and it really just a matter of opinion. I personally don't think there is much of a noticeable difference between the fillings however synthetic fibers will not absorb water and will keep you warmer even if the bag is a bit wet. A wet down sleeping bag is very hard to dry out and is considered worse than having no sleeping bag at all. In cases where you're in a survival situation synthetic is definitely the choice you should go with. Wool tends to stay dry however it is much heavier and is harder to transport because of that extra weight. Synthetic will keep you warm however it tends to compress easier and the bottom of the bag will let cool air in because of this. Hanging them and changing the position when storing is the preferred method of many outdoor enthusiasts as this keeps them from forming dead spots where the fibers have been crushed and rendering them ineffective at keeping you warm on cold evenings.
Now while there are other things to consider in buying a sleeping bag, these are the most important. Having this information alone will help you to choose the perfect sleeping bag for a comfortable night's rest during your next overnight outdoor adventure.
Lastly, you might want to consider portability, compactness - ease of carrying your sleeping bags. Your bags should not be greater than three pounds for carrying. Neither should it be too big according to your carrying capacity (Except if you are going winter camping with expected bigger winter bags). There are compression sacks for bulky bags but remember that this could damage the bag's filling in the long run and affect its insulation. The most compressible sleeping bags are down bags. You can fit them in a backpack.
