ThermalCore warmth without the weight

ThermalCore insulation uses multiple TRM layers designed to quietly reflect infrared energy back to the sleeper. This approach adds warmth where you need it while keeping the overall weight and bulk down, so you can carry a capable pad without feeling weighed down.

• ThermalCore insulation with TRM layers quietly boosts warmth
• Extended 3 season capability with an ASTM-tested R-value of 4.1
• 10 cm (3.9 in) thick for plush, stable comfort in any sleeping position

Smart design that makes camp life easier

Inflation and deflation are streamlined thanks to an integrated Airstream pump built into the stuff sack and a high‑airflow XPRESS valve. This combination helps you get to sleep faster and reduces fiddling at camp, so you can focus on the moment rather than the setup.

• XPRESS valve and pumpsack integrated into the stuff sack for quick inflation
• Effortless deflation and compact packing when you’re ready to move

The pad’s lightweight construction and compact packed size improve backpack and pannier carry, making it a practical choice for backcountry trips where every ounce matters. The rectangular large shape offers a spacious, stable sleep surface that adapts to various sleeping styles, helping you rest more soundly after long days outdoors.

In short, the Ether Light XR blends warmth, comfort, and ease of use into a single sleeping solution designed for 3‑season adventures. It’s a dependable companion for campers who value a restful night as a foundation for the next day’s miles, without adding unnecessary weight or bulk.
