Ether Light XR insulated large inflatable sleeping mat

The Sea to Summit Ether Light XR insulated large inflatable sleeping mat is lightweight, very comfortable and insulating. Ideal for lightweight hiking and comfortable cold-weather sleep thanks to an extra insulating layer.
This large version suits taller people, and those seeking greater comfort, room to move at night or space to rest their arms when sleeping on their back or stomach.

Comfort and insulation

The ideal inflatable mat for hikers who sleep on their side. Its 10 cm thickness and independent cell construction stop the hip sinking too far.
The Ether Light XR insulated mat uses Air Sprung Cells technology: cells are entirely independent, with just one wall joining the top fabric to the ground-facing fabric. This provides good stability through the night. Using less fabric also saves weight.
For cold insulation, the mat has several layers called TRM, quiet aluminised films. These reflect body heat and reduce heat transfer between hiker and ground.

Attachments on the mat hold the Sea to Summit Aeros pillow in place all night.

Tough materials

The materials and construction are tough, making it suited to all-terrain use.
The 30/40D nylon fabric resists snags, the internal TPU layer has an antimicrobial treatment to keep the mat hygienic, and the outer fabric's PU coating reduces noise and slipping while retaining a soft feel.

This lightweight inflatable sleeping mat has a clever multifunction valve:
A non-return valve lets you inflate the mat easily without losing pressure.
For deflation, the valve offers two options: release air incrementally by pressing the non-return valve to adjust firmness before use, or deflate completely for packing. 

Storage sack with integrated inflation system and repair kit included.

The storage bag doubles as a pump sack for very quick, effortless inflation.
The repair kit includes 6 self-adhesive puncture patches and a replacement non-return flap for lasting use.
