The other sacrifice is the size or thickness of the bag. A mummy sleeping bag essentially will certainly be much smaller sized for bring around which is why it is a preference for many backpackers/hikers. The rectangular resting bag isn't as small yet because it's not common to be lugging it, apart from somewhere in a vehicle while getting to your intended location, the bulkiness of the bag is not as large a problem.
The definition of a sleeping bag is a protective bag for an individual to sleep in. Some people may not like the feel of sleeping in a normal rectangle-shaped shaped bag, choosing the closeness of a conical one, whereas others could feel too claustrophobic. Camping resting bags are a lot more compared to simply resting bags. They are the determining factor of whether your outdoor camping trip is an enjoyable one.
The trouble is that when I went to look for my "ideal bag" there was so many choices I really did not know which bag would certainly function best for me. One is the mommy bag and also the various other is the "old school" rectangular sleeping bag. The rectangular sleeping bag isn't as tiny however given that it's not regular to be carrying it, other compared to somewhere in a car while obtaining to your designated destination, the thickness of the bag is not as big an issue.
