Mummy sleeping bags are popular with adventurists, mountaineers, and backpackers mostly because they trap air tightly to the body. The drawstring hood can be tightly tied to keep the face and head warm. Mummy bags work best when you place a sleep pad underneath them to add a layer of insulation between you and the ground.
Another tip is to wear thermal underwear to trap your body heat inside the sleeping bag. Mummy bags compress tightly and add very little weight to the backpack. Be sure to check the temperature rating before your trip. Choose a bag for temperature that is slightly lower than the temperatures you expect. Of course, you can always snuggle up in a double sleeping bag for two people that'll keep you warm and snuggly with your partner.
If you have children we recommend these for your toddlers or these for your older kids.

Mummy Sleeping bags vs. Rectangular Sleeping Bags
When looking for a sleeping bag for camping in cold temperatures, shape matters. The tighter the sleeping bag is to your body, the less chance there is for cold air to enter the empty space. Your body heat radiates and reflects heat to help keep you warm. The sleeping bag forms a barrier between your warm body and the cold air outside.
Novice campers may be quick to grab a rectangular sleeping bag because it is the style that they are most familiar with. The most obvious benefit to choosing a rectangular-shaped bag is that there is a lot more room, especially for your feet. Rectangle bags are great for active sleepers. That may be fine when camping in reasonably good weather. If the temperatures turn cold, campers will stay warmer in a barrel-shaped or mummy-style bag.
If you’re truly looking to stay warm while you sleep at the campsite, you can’t go wrong with a mummy-style sleeping bag. Mummy bags are narrower near the shoulder and hip areas to take advantage of warmth, while reducing size and bulk. The down side is that what you gain in warmth, you lose in the ability to move around while you sleep.
