The basic rectangular design works well for most camping needs and is comfortable in moderate to warm climates. Rectangular sleeping bags are fitted with a zipper on three sides allowing them to be folded in half and secured in this position. After use, rectangular sleeping bags are easily packed by folding into thirds, rolling up, and being bound by straps or cords. An additional feature offered with some rectangular bags is the capability to zip two bags together to make one large sleeping bag. Take a look below at our selection of rectangular sleeping bags.
