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 Regular version with a length of 183 cm .
