The NeoAir XLite NXT and XTherm NXT are the same pad tuned to different seasons, so the decision is simple to frame: do you need four-season warmth, or would you rather save weight and money for three-season conditions?

This is a three-season versus four-season decision, and neither pad is the loser. The XLite NXT is the classic ultralight benchmark for backpackers who spend their nights above freezing and want the lightest, cheapest pad that still keeps them warm. The XTherm NXT is the winter and shoulder-season version, built for cold ground and colder nights. They come from the same family and feel the same underfoot, so the split really is just about how cold it gets where you sleep.
On paper the difference is easy to read. The XLite is lighter and cheaper with three-season warmth, while the XTherm is warmer at a small weight and price premium. A few ounces and a little more money buy a large jump in warmth, enough for winter use, plus a tougher, burlier floor and added inflation and valve hardware. Both pads are the same thickness and both inflate with the same pump sack, so comfort and setup are a wash.
Pick the XLite NXT if you're a three-season backpacker chasing low weight and cost, and its three-season warmth covers the conditions you actually sleep in. Pick the XTherm NXT if you camp in real cold, on frozen ground, or through the shoulder seasons, where its four-season warmth and burlier floor earn their keep. And if you camp year-round, plenty of people just buy the XTherm and carry the small weight penalty through summer rather than own two pads.
For three-season backpacking where nights stay above freezing, the XLite NXT is the pick. It's lighter, cheaper, and its three-season warmth is plenty. Choose the XTherm NXT if you need four-season warmth. It handles winter and frozen ground for a small weight and price premium.
Yes, that's what it's built for. Its warmth is a true four-season rating, paired with a tougher floor for cold, rough, or frozen ground. The XLite, by contrast, is a three-season pad.
Only a little. The XTherm NXT weighs a few ounces more than the XLite NXT. In return you get a big step up in warmth, from three-season into true four-season, plus a more durable underside. Both pads share the same thickness.
