Sea to Summit Ether Light XR Insulated Air Sleeping Mat - Small
The SEA TO SUMMIT Ether Light XR mattress has been designed specifically for side sleepers, thanks to the extra thickness (10 cm) allowing your hip to sink into the mattress without touching the ground. An evolution of the XT, the Ether Light XR is lighter and more compact while displaying a significantly increased R-value (4.1) thanks to its Thermal Core insulation. It is thus equipped with a layer of reflective film suspended between the mattress's point welds. This film reflects radiant heat back towards the sleeper and minimizes air movement inside the mattress, thus ensuring effective insulation. The integrated Airstream pump and high-flow Xpress valve provide ultra-fast, ultra-easy inflation and deflation It is offered here in a Small version with a length of 168 cm .
