At first, a sleeping bag was nothing more than a blanket you wrapped around yourself. Because of technology zippers were made. Obviously the next advancement in the sleeping bag world was a blanket that could be closed up by a zipper. You may think by examining a sleeping bag in today's market that not a whole lot has been altered simply because a sleeping bag still definitely looks like a blanket with a zipper up the side right? wrong.
It's what's inside that matters
Clearly, sleeping bags will no longer be seen as simply a blanket. Manufacturers have formulated double layer fabrics which happens to be filled to create an insulation pocket you sleep in. Numerous companies fill up this pocket with various materials. Some examples are "high loft European downs" and synthetics just like "DuPont Thermolite" and "Powerloft 3D". Typically this all goes down to 2 kinds, down and synthetic.
These kind of materials are developing on a regular basis, right now a material just like "Down" that is able to get wet and still retain it's warmth is being designed. If this works it will be a significant breakthrough..
Strong exterior
As fabric technology gets better so does the outer material of the sleeping bag structure. Materials like super strong nylon and polyester are used. This has developed to breathable fabrics and fabrics that fight tears and ripping.
Progression
How much progress did the sleeping bag go through? Have you heard that you can get a sleeping bag which you may slip on like a full body jump suit. This ingenious style mixes movability and comfort.

Temperature Ratings
Different folks produce completely different body heat. This is exactly why sleeping bags have a variety of temperature ratings. It's encouraged that you select a bag depending on the coldest environment you're likely to go. The task of the insulating material inside your sleeping bag is to build a barrier between the warm air that your own body heat produces and the cold air outside the bag. The stronger the barrier the warmer the bag is going to be.
Down is the most reliable filling for its weight and packed size but it is at the same time the priciest, so it is perfect for bushwalkers, trekkers and even travellers. One problem with Down is if in case it gets wet it does not retain its thermal properties.
Synthetic insulations are generally measured in grams in every square metre and the more filling the warmer the bag will undoubtedly be having said that it will also be heavier and bulkier.
Science says - It will all depend on you
