The Therm-a-rest Neo Air XLite is an extremely impressive ultralight sleeping pad that performed well in all criteria. Its warmth and durability were a pleasant surprise considering its average R-value rating and for it being an ultralight mat.
Comfort The horizontal baffles and its firm shape create the illusion of the Neo Air being much thicker than its 2.5 inches. The narrow tapered foot proved to be uncomfortable for side sleeping.
Weight Thermarest was conservative in rating the The Neo Air at 12oz. Our scales showed it at 11.8oz making it the lightest pad in this test. It packs down to be about the size of a 1L Nalgene water bottle.
Warmth The reflective foil and double layer of inner baffles proved to work well even on a cold hard surface. The R Value seems to be rated on the moderate side, as its warmth was surprising.
Durability The NeoAir is made of 30D Nylon. Despite the pad being ultralight and it feeling more delicate, the pad proved to be durable on all testing surfaces. Note: The D, standing for Denier, essentially means the weight of the fabric (or thickness of thread used).
Ease of Use The Therm-a-rest NeoAir uses a one-way valve, which takes more than a couple minutes to inflate by mouth. It was quite slow to deflate and proved to be difficult to get all of the air out of the pad.
