Therm-a-Rest NeoAir XLite NXT Sleeping Pad Review
Searching for a lightweight, packable sleeping pad that performs in cool conditions? In this Therm-a-Rest NeoAir XLite NXT Sleeping Pad review, we look at why this ultralight favorite continues to set the standard for backpacking performance.
The Therm-a-Rest NeoAir XLite NXT Sleeping Pad builds on the success of the original XLite with improved warmth, reduced noise, and a thicker 3-inch profile. With an R-value of 4.5 and a weight of just 13 oz (regular size), it strikes a near-perfect balance between insulation, comfort, and portability for 3-season and shoulder-season trips.
Its triangular core matrix baffle construction traps heat efficiently and minimizes convective heat loss, while also providing a stable sleep surface. One major upgrade in the NXT version is reduced crinkling—this pad is noticeably quieter than its predecessor, a welcome update for light sleepers. The WingLock™ valve allows for fast inflation and deflation, and the pad packs down to the size of a water bottle.

Comparisons
Therm-a-Rest NeoAir XLite NXT vs. Sea to Summit UltraLight Insulated
The Sea to Summit UltraLight Insulated Sleeping Pad is slightly heavier at 15 oz, and thinner at 2 inches, but it’s also quieter and features a softer, more comfortable surface for back sleepers. However, the Therm-a-Rest NeoAir XLite NXT Sleeping Pad is warmer with an R-value of 4.5 vs. Sea to Summit’s 3.1, and it weighs less. While the Sea to Summit is more budget-friendly and comfortable for light trips, the NeoAir XLite NXT is better suited for colder shoulder-season conditions and anyone counting ounces.
Therm-a-Rest NeoAir XLite NXT vs. NEMO Tensor Extreme Conditions
The NEMO Tensor Extreme Conditions Sleeping Pad is warmer overall (R-value 8.5) and quieter, but it’s also heavier at about 17 oz and more expensive. The Therm-a-Rest NeoAir XLite NXT Sleeping Pad is lighter and more packable, making it a favorite for thru-hikers and ultralight backpackers. If you camp in truly cold weather, the Tensor wins on insulation. But if you’re looking for a lighter pad with solid warmth for most conditions, the XLite NXT strikes the better balance.
