The Sea to Summit Ultralight Insulated Small Mat manages to do something pretty unique. It's lighter and more packable than a lot of self-inflating sleeping mats on the market, thanks to single-layer construction that uses a network of medium-resolution cells to keep you cushioned without adding unnecessary weight. It does that thanks to the AirStream Pumpsack built into the stuff sack, allowing you to quickly and easily inflate the mat even without bringing any extra gear. And once it's inflated, it's warmer too, thanks to the ThermoLite® insulation filling every Air Sprung Cell™, and Exkin® Platinum reflective material found at every dot weld.
KEY FEATURES- ThermoLite® fill inside the mat prevents the cold ground from pulling warmth away while you sleep
- Exkin® Platinum Dot Welds reflect body heat back to you for increased cold-weather comfort
