- 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.
