Our take on the Sea to Summit Ether Light XR Large Rectangular Sleeping Mat

The Ether Light XR is Sea to Summit's large rectangular inflatable sleeping mat, 198 cm long and 10 cm thick, built for car campers and taller sleepers who want room to move. It uses an air-sprung cell construction with a quiet, stretchy face fabric and a multi-function valve for fast inflation and fine pressure tuning. At $196.25 at Scandinavian Outdoor as of November 7, 2026, it sits at the low end of its recent range across the three stores that carry it.

Pros
  • 10 cm thickness gives real clearance for side sleepers' hips and shoulders
  • 198 cm length suits taller users without feet hanging off
  • Rectangular shape gives full usable area edge to edge
  • Multi-function valve makes inflation, deflation and pressure tweaks quick
  • Quiet face fabric reduces the crinkle and rustle of older air mats
Cons
  • Large rectangular size packs bigger and weighs more than tapered mummy mats
  • Not the warmest choice for cold-weather or winter camping
  • Air-sprung cells can feel bouncy to sleepers used to foam mats
  • Price sits near $200, well above basic inflatable pads

Questions and answers

Is the Ether Light XR good for side sleepers?
Yes. At 10 cm thick it gives side sleepers enough clearance for hips and shoulders, which is the main reason owners recommend it.
How does it compare with the regular Ether Light XT?
The XR is the large rectangular version, longer at 198 cm and with full-width corners. The XT line is lighter and more tapered for backpacking.
Is it warm enough for winter camping?
No. It is a three-season mat at best; for freezing conditions pair it with a warmer pad or a high-R-value inflatable.
What's in the box?
The mat, a stuff sack and a repair patch. A pump sack is not included, so bring one or inflate by mouth through the valve.
When is it cheapest?
Its best new price was $196.25 at Scandinavian Outdoor as of November 7, 2026, near the low end of its recent range. Watch for end-of-season sales.
