Mummy shaped sleeping bags are the most common style of sleeping bag you'll come across, and if you want to ensure your child is nice and warm during the night, choosing a mummy shaped sleeping bag for your child is a must. Mummy shaped sleeping bags have a tapered shape, which minimises on empty space inside. When sleeping bags have empty space inside, this creates cold spots within the sleeping bag and doesn't provide as good a level of insulation.
Mummy shaped sleeping bags also hug your body & feature hoods for a more cosy feel & added insulation. Another benefit to mummy shaped sleeping bags compared to rectangle shaped bags is that they use less material due to their tapered shape, this makes them more compact when they are packed into their storage stuff sack, so kids can carry them easily!
I recently went camping in scotland , the temperature was a little over freezing , i found the bag to be reasonably comfortable and warm , i had a great nights sleep , i also tried the mosquito net , i found the zips a little hard to do as the bag does not have much room to manoeuvre around in , once the net was zipped up the bag felt too claustrophobic for me to sleep all night with it done up, however had there been a true need for the net im sure i could have gotten used to it , the only issue i had was the bag it came in is very poorly made & the stitching broke the first time i rolled it up and put it away , overall i am happy with my purchase and would recommend it to any casual camper for short term use.
