Therm-a-Rest NeoAir XTherm NXT vs Therm-a-Rest NeoAir XLite NXT

Both pads share the same 3-inch thickness, WingLock valve, pump sack and packed footprint, so the choice comes down to warmth versus weight. The XTherm NXT carries an R-value of 7.3 at 15.5 oz, which makes it the cold-weather pick for snow camping and mountaineering. The XLite NXT is lighter at 13 oz with an R-value of 4.5, enough for three-season use, and it comes in a Short size the XTherm no longer offers. Owners of both report valve and air-loss problems, and the XLite's slick surface lets sleepers slide; the XTherm rates higher with buyers overall.

  • Choose the NeoAir XTherm NXT if you sleep on snow, camp in shoulder-season cold, or want the most warmth per ounce and can accept a few extra ounces.
  • Choose the NeoAir XLite NXT if you mostly backpack in three seasons, want the lightest packed pad, or need a Short length.

What reviewers say

Therm-a-Rest NeoAir XTherm NXT

  • 4.2 / 5105 ratings

Owners rate it highly for warmth and weight, calling it a reliable cold-weather pad that works on snow. Complaints center on valve leaks, overnight air loss and the loss of a short size.

What people mention
  • WarmthPraisedOwners say the 7.3 R-value keeps them warm in freezing conditions and on snow.
  • WeightMixedPraised as ultralight for its warmth, though some note the NXT is heavier than the older XTherm.
  • ValveCriticisedSeveral owners report valve leaks, sometimes shortly after the warranty ends.
  • Air retentionCriticisedSome sleepers wake to a partly deflated pad and have to reinflate during the night.

Therm-a-Rest NeoAir XLite NXT

  • 3.9 / 5161 ratings

Owners rate the XLite NXT well for warmth, weight and comfort, and many say the noise reduction is real. The recurring complaints are pads that fail to hold air and a slick surface that lets bags slide.

What people mention
  • Weight and pack sizePraisedOwners like that it disappears into a pack and packs near the size of a water bottle.
  • WarmthPraisedThe 4.5 R-value is reported to keep sleepers warm on cold nights.
  • NoiseMixedMost say it is far quieter than the previous model, but some light sleepers still notice it.

Questions and answers

Which is better for winter camping?
The XTherm NXT. Its R-value of 7.3 is built for snow and sub-freezing ground, while the XLite's 4.5 is a three-season rating.
Is the XLite warm enough for cold nights?
For spring through fall, yes. Below freezing, most sleepers will want the XTherm or an added closed-cell pad under the XLite.
Which one lasts longer?
The XTherm's 70D bottom resists abrasion better than the XLite's 30D shell. Both share the same valve design, and owners of both report leaks, so treat the valve as the weak point.
Is the XTherm worth stepping up to?
If you camp in real cold, yes. You gain 2.8 R-value for about 2.5 oz. If you stay in three seasons, the XLite's lower weight and Short size make more sense.
Which is quieter?
The XTherm draws fewer noise complaints. The XLite is much quieter than its prior version but still bothers some light sleepers.
Do they come in the same sizes?
No. The XLite adds a 66-inch Short; the XTherm comes only in Regular and Large, both available in 20- and 25-inch widths.
