Sea to Summit Etherlite XR Thermal Core Mattress

Introduction

Ether Light XR is the thickest and warmest sleeping mat in our Ultra Light range, due to using new insulation, Thermal Core. The Air Sprung Cells still provide four inches of stability and comfort, while Thermal Core insulation prevents convective heat loss and internal air movement. This results in true four-season performance perfect for backpacking, light weight camping, bikepacking and sea kayaking.
