Afterpay – How it works
The Ether Light XR Insulated Air Sleeping Mat uses ThermalCore® insulation with quiet, lightweight and grippy fabric and 10cm-high Air Sprung Cells for comfort in colder conditions. Other features include a XPRESS valve for easy inflation, deflation and fine tuning, an Airstream™ pump integrated into the stuff sack for quick inflation and the PillowLock system to hold your Sea to Summit pillow in place. The extra height of the mat makes it ideal for side sleepers so your hip stays off the ground during your sleep.

ThermalCore® Insulation: uses a single or multiple layers of TRM material to reflect warmth back to the sleeper. The TRM layers reduce internal air movement, and the smaller die cuts, compared to prior models, reduce this further still. The result is a significant increase in both R-Value and in real-world insulation performance, while reducing weight and packed volume.

XPRESS Valve: made to make inflation, deflation and adjustment of its air mats quicker and simpler than conventional air mats. The valve integrates a one-way inflate port, a rapid dump deflate port and a fine-tune button into a single, low-profile unit. The XPRESS valve fits the nozzle of the Airstream pump integrated into the stuff sack supplied with your Sea to Summit Air Spring Cell sleeping mat. Pro Tip- turn the inflator bag of the sleeping mat pump inside out to reveal a nozzle sized perfectly for the mini-XPRESS valve of an Aeros Pillow
