Industry-Leading Warmth-to-Weight Ratio with Unrivaled Backcountry Comfort

The Therm-a-Rest NeoAir XLite NXT sets the gold standard for ultralight alpine performance, refining the legendary XLite series with increased thickness and significantly reduced noise. Engineered for year-round reliability, this pad utilizes Therm-a-Rest’s proprietary Triangular Core Matrix™, which creates a complex internal structure that traps heat with incredible efficiency. Achieving an impressive 4.5 R-value, it provides exceptional insulation from frozen ground while maintaining a featherlight profile that fits effortlessly into any backpacking setup.

The NXT upgrade introduces a 3-inch thick loft, offering enhanced stability and superior cushion for side sleepers or those traversing uneven terrain. Beyond the improved dimensions, Therm-a-Rest has meticulously engineered the internal construction to eliminate the infamous "crinkle" noise of previous iterations, resulting in a noticeably quieter, more restorative night’s sleep. The included WingLock™ Valve features high-flow inflation and rapid deflation, allowing you to fine-tune your firmness with ease. Whether you are tackling a multi-month thru-hike or a technical climbing expedition, the XLite NXT provides the confidence of a warmer, thicker, and quieter night under the stars.
