Sea To Summit Ether Light XR Insulated Sleeping Mat Large Rectangular Grey

Built for ultimate comfort in the wild, this large, rectangular, 10cm thick sleeping mat combines Air Sprung Cell technology, advanced Thermal Core insulation, and a smart XPRESS valve for effortless setup and a cosy night under the stars.

The Sea To Summit Ether Light XR Insulated Large Rectangular Sleeping Mat provides the ultimate sleep experience in the wild. With its 10cm thick structure, this mat utilises Air Sprung Cell technology for plush, personalised comfort, with the flexibility to contour to your body. The Air Sprung Cell air pockets result in a sleeping mat that is thicker while saving weight, making it adventure-ready. The 4.1 R-Value and ThermalCore insulation tackle cold conditions, featuring a suspended TRM layer that redirects heat back to keep your body warm, while the PillowLock system ensures your pillow stays in place all night. Crafted with lightweight, durable 30D/40D fabric, this sleeping mat offers a quiet, cosy retreat wherever your adventures take you. The XPRESS valve features a one-way inflate port for worry-free inflation and user-friendly fine tune button to personalise the pressure. When you’re ready for your next destination, the rapid air-dump deflate port makes it easy to roll up and go without air re-entering.
