What is the purpose of the raised material along the neck of your sleeping bags?Updated 8 months ago

The raised material along the neck of certain TETON Sports sleeping bags is called a shoulder draft tube. This insulated tube is designed to block cold air from entering the sleeping bag, particularly around the shoulders, where heat can escape. By sealing in warmth, the draft tube enhances your comfort and helps keep you cozy on cold nights. It's one of the key features designed to ensure a warmer, more comfortable experience during your outdoor adventures.
