Buying a new mummy 4 season sleeping bag? Here are some things we think that you should know. 4 season sleeping bags come with extra insulation for sleeping outdoors in all four seasons, so you can sleep warmly even if the ground is covered in snow. They are designed with an insulated hood that can be cinched down around your head, ensuring you'll retain heat and remain cozy in even the most extreme environments. However, they have more expensive price tag than 2 or 3 season sleeping bags, which might not be worth the investment if you aren't an avid camper or hiker. They weigh less than rectangular bags, so you won't have to sacrifice warmth over weight. However, these sleeping bags provide less space to move around, making them less suitable for sleepers who toss and turn. On the other hand, they create a snug and tight fit that helps trap body heat and keep you warm, providing maximum warmth, since their tight fitting cut is designed to trap body heat.
