We've looked at hot weather rectangular sleeping bags and wanted to let you know about them. Rectangular sleeping bags have a roomy design, making them great for people who feel too confined by the tight mummy shape. They accommodate varying sleeping positions, allowing you to sleep in any position you choose. With double zippers, they are perfect for a cozy night of sleeping for two as you can attach two sleeping bags to each other. However, they are not very heat-efficient, allowing the cool air to circulate since they have a more spacious design. In addition, these sleeping bags are quite heavy, so they may weigh you down on long backpacking trips. They are typically made with synthetic insulation, so they insulate even when they are wet.
