The Therm-a-Rest NeoAir XTherm has been the gold standard for backpacking sleeping pads for years, and the current version cements that position with an R-value of 7.3 that handles everything from summer trails to winter snow camping. At 15 ounces for the regular size, it delivers four-season warmth in a package lighter than most three-season competitors. The proprietary Triangular Core Matrix baffles trap heat in triangular reflective cells that minimize convective heat loss, a design unique to Therm-a-Rest that gives the XTherm its extraordinary warmth-to-weight ratio.
Comfort is very good for a 2.5-inch-thick pad. The narrow baffles provide stable support that prevents the side-to-side rolling common on wider baffle designs. Back sleepers find it excellent, and stomach sleepers report solid support. Side sleepers under 180 pounds sleep comfortably, though heavier side sleepers may notice some pressure at the hips. The 20-inch width is standard for mummy-style pads and fits inside most backpacking tents without issues. The 30D ripstop nylon top and 70D bottom fabric strike a strong balance between packability and durability, with the heavier bottom fabric protecting against ground abrasion.
The included pump sack inflates the pad in three to four fill cycles and keeps breath moisture out of the internal baffles, which is critical for maintaining R-value in cold conditions. The WingLock valve is firm and reliable, holding air without the slow leaks that plague some competitors. Packed down, the XTherm compresses to roughly the size of a one-liter water bottle, making it easy to fit inside a backpacking pack alongside a sleeping bag and shelter. At $250, the XTherm is a significant investment, but no other pad on the market combines this level of warmth, this low weight, and this small packed size. For backpackers who camp across all four seasons, it eliminates the need to own multiple pads.
