Therm-a-Rest NeoAir XTherm NXT review

The NeoAir XTherm NXT is the pad to buy if you camp on snow or frozen ground. Therm-a-Rest rates it at 7.3 R, the highest on this list, while the Regular size weighs 15.5 oz (440 g), only 2.5 oz more than the XLite NXT. It shares the 3 in. (7.6 cm) baffled profile and ThermaCapture layers, but swaps in 70D nylon on the bottom for durability on rough winter ground and keeps a 30D ripstop top to save weight. The WingLock valve is designed to work with gloves on, and the pump sack, stuff sack and repair kit are included. Exped notes that ISO sleeping bag ratings assume a 7R mat, which puts the XTherm in range for using a bag at its rated temperature. It ranks fourth overall only because $229.95 buys more warmth than most three-season campers will use. We compared documented features and published prices and did not test the pad.
