Our article will highlight the key specs to consider when buying a double rectangular sleeping bag. These sleeping bags have a very roomy design, so they are ideal for people who feel too claustrophobic by the tight mummy shape. They accommodate varying sleeping positions, giving you plenty of room to get comfortable, regardless of your sleeping position. Rectangular sleeping bags have double zippers, so they can double as a quilt. However, they are less ideal for cold weather, allowing the cool air to circulate since they have a more spacious design. Additionally, they are quite heavy, so they are often bulkier and less comfortable to carry long distances. They are suitable for more than one person, so you can stay warmer using the combined body heat of you and your partner. Double sleeping bags have a design that is good for car camping, which makes them great for when you'll be reaching the campsite with your vehicle, and not by foot. However, they take up a lot of space, so they are less compact and harder to carry on your back.
