With a generous shape, these sleeping bags are ideal for those who like plenty of room to stretch out. They accommodate varying sleeping positions, so if you move around a lot at night, you'll have the space and freedom to sleep in any position you choose. Rectangular sleeping bags feature double zippers, so they can double as an over blanket. However, they are not very heat-efficient, allowing the cool air to circulate since they have a more spacious design. Moreover, they are quite heavy, so they are often bulkier and less comfortable to carry long distances.
