Our air pads have been redesigned and improved for 2007. All of our pads are still heat bonded and use polyurethane open cell foam. They still inflate/deflate very fast and easy because of the JetStream Foam. Our comfort series pads also feature anti-slip "pvc dot" bottom fabric that prevents your pad from sliding around your tent. A non-corrosive brass valve is used for maximum durability. A FREE stuff sack and repair kit are included with every pad ... something many other companies make you pay extra for. The weight of this pad is 4 lb. 6 oz. and the packed size is approximately 6.5" x 26". These pads are a tremendous value and will provide you with many years of comfort.
