  • Very efficient in cold weather
  • One person only sleeping bag
  • Light weight, often ultra compact
  • Zip is usually a 3/4 zip
  • Can handle temperatures in the minus degrees depending on fill

The Pros and Cons

The pros of square bags and mummy bags will help you make a choice between which style best suits your individual needs. At the end of the day, you need to decide what your needs are, what type of camping are you doing, do you require room to move in your sleeping bag etc….

Square bags aren’t a good pick for most backcountry travelers. Sleeping bags of this kind aren’t suitable as they are generally heavier and bulkier, adding unnecessary weight to your back pack.

Although roomy and inexpensive, their design allows a lot of body heat to escape. On the other hand, many people find square sleeping bags much more comfortable as there is room to stretch and move with ease. But again, they don’t pack down as tightly as a mummy sleeping bag.

Mummy bags are designed to maximize heat retention and save weight. They are much narrower towards the feet, the shoulders are flared out and tapered to a fitted drawstring hood.

The close-fitting bag offers increased warmth in comparison to square sleeping bags. Most of the mummy bags do not have a zip running all the way to the feet. Zippers may prove to be a weak point in the insulating qualities of any sleeping bag.
