The Sea To Summit Ether Light XR Pro Insulated Regular Rectangular Wide Sleeping Mat provides top-of-the-line strength and warmth from the Ether Light range, ready for all seasons including for winter camping and mountaineering. 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 7.4 R-Value and ThermalCore insulation can tackle alpine conditions, featuring several TRM layers that redirect heat back to keep your body warm. The PillowLock system ensures your pillow stays in place all night. Crafted with lightweight, durable 30D/40D nylon 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.
