What is a baffle?
• There are two types of baffles on LEDGE sleeping bags. A zipper baffle is an insulated tube that runs along the length of the zipper and keeps warm air from escaping through the zipper and keeps cold air out of the sleeping bag. A shoulder baffle is an insulated tube collar that you can cinch up around your neck and shoulders to keep warm air in and cold air out from the body of the sleeping bag.
