Thermarest XLiteNO IMAGE FOUND!
Thermarest's Neoair XLite replaces the original Neoair pad, offering upgraded warmth (from a spec value of R2.4 to R3.2) at a slightly lower weight—one ounce less overall. The weight differential isn't really big news, but the added warmth is: an R-value of 3.2 is pushing into the 4-season category, and even for 3-season use, you will absolutely notice and enjoy the extra warmth.
