Two official Regular NeoAir NXT pads with the same 72 × 20 × 3 in outline. The documented trade is a lower official weight and price versus a higher official R-value and a tougher official bottom fabric.

Key facts at a glance
| Therm-a-Rest NeoAir XLite NXT | Therm-a-Rest NeoAir XTherm NXT | |
|---|---|---|
| Official price (fetched Nov 10, 2026) | $199.95. CleverHiker listed $210 | $229.95. CleverHiker listed $230. OutdoorGearLab, March 23, 2026, listed $240 |
| Official Regular weight | 13 oz / 370 g. CleverHiker also listed 13 oz for the Regular | 15.5 oz / 440 g. CleverHiker measured 16 oz on a Regular mummy. OutdoorGearLab weighed the pad at exactly one pound (16 oz). We report that 0.5 oz disagreement with the official figure |
| Official R-value / thickness / size | R-value 4.5; 3 in / 7.6 cm thick; 72 × 20 in / 183 × 51 cm. Official copy also calls this “year-round” and “4-season ready.” CleverHiker, last updated September 21, 2026, still treats it as a three-season pad and would not choose it as a standalone winter pad | R-value 7.3; 3 in / 7.6 cm thick; 72 × 20 in / 183 × 51 cm. Official copy describes it as a cold-weather / expedition pad |
| Official packed size | 9 × 4.1 in / 23 × 10 cm | 9 × 4.5 in / 23 × 11 cm. CleverHiker listed roughly 4.5 × 9 in for the Regular |
| Official fabrics / valve / includes | 30D ripstop HT nylon top and bottom; WingLock valve; pump sack, stuff sack, and field repair kit; official Limited Lifetime Warranty language on the product page; made in USA of U.S. and imported materials | 30D ripstop HT nylon top and 70D nylon bottom; WingLock valve, with official glove-use language; the same official includes list and Limited Lifetime Warranty language; made in USA of U.S. and imported materials |
We compared these pads using Therm-a-Rest’s official NeoAir XLite NXT and XTherm NXT product pages, both fetched November 10, 2026, plus CleverHiker’s XLite NXT and XTherm NXT reviews, both last updated September 21, 2026, and OutdoorGearLab’s XTherm NXT review dated March 23, 2026. Official Regular prices were $199.95 and $229.95. Both official Regular pads are 72 × 20 × 3 in with a WingLock valve. The question here is whether you want the official 13 oz / R-4.5 XLite or the official 15.5 oz / R-7.3 XTherm, not which pad beats the NEMO Tensor. That Tensor comparison already lives on another page. We have not slept on either NXT pad. We do not republish numeric scores. Official R-values on these pages are presented under the ASTM F3340-18 discussion Therm-a-Rest publishes on the same product pages.
Choose the XLite NXT if you want the official lighter, less expensive Regular pad at $199.95: official Regular weight 13 oz / 370 g, ASTM R-value 4.5, 3 in thick, 72 × 20 in, packed 9 × 4.1 in, and 30D ripstop nylon on both sides, with a pump sack, stuff sack, and field repair kit included. Official copy also calls that 4.5 R-value “year-round” and “4-season ready.” Choose the XTherm NXT if you want the official warmer, tougher-bottom Regular pad at $229.95: official Regular weight 15.5 oz / 440 g, R-value 7.3, the same official 72 × 20 × 3 in outline, packed 9 × 4.5 in, 30D ripstop on top and 70D nylon on the bottom, plus the same official includes list. We have not slept on these pads, and we don’t give scores. This is a Regular-to-Regular comparison, not an XLite vs Tensor remake, and it is not the MAX rectangular versions. CleverHiker reviews of both pads, last updated September 21, 2026, listed $210 and $230 and measured the XTherm Regular at 16 oz, 0.5 oz above the official 15.5 oz figure. OutdoorGearLab’s XTherm review, dated March 23, 2026, listed $240 and also weighed the pad at exactly one pound (16 oz). We cite the official prices and weights and report those disagreements. CleverHiker would not choose the XLite as a standalone pad for genuinely cold winter camping, despite the official “4-season ready” language — we report both.

What are the pros and cons?
Therm-a-Rest NeoAir XLite NXT: pros
- Lower official Regular price ($199.95) and a lighter official Regular weight (13 oz)
- The same official 72 × 20 × 3 in outline as the XTherm, with a slightly smaller official packed size
- CleverHiker, last updated September 21, 2026, still lists 13 oz and treats it as a strong lightweight three-season pad
Therm-a-Rest NeoAir XLite NXT: cons
- Lower official R-value (4.5 vs 7.3) and official 30D fabric on both sides, rather than the official XTherm 70D bottom
- Official “4-season ready” language disagrees with CleverHiker’s judgment that it is not their standalone winter pad — we report both
- CleverHiker listed $210, $10.05 above the official $199.95 we fetched
Therm-a-Rest NeoAir XTherm NXT: pros
- Higher official R-value (7.3) at a modest official Regular weight of 15.5 oz
- Official 70D nylon bottom, which CleverHiker and OutdoorGearLab both discuss as a durability advantage
- Same official Regular outline and WingLock system as the XLite
Therm-a-Rest NeoAir XTherm NXT: cons
- Higher official Regular price ($229.95) and a heavier official Regular weight (15.5 oz)
- CleverHiker’s 16 oz measurement and OutdoorGearLab’s 16 oz / 1 lb scale weight disagree with the official 15.5 oz figure
- OutdoorGearLab’s March 23, 2026 $240 list price disagrees with the official $229.95
Which should you choose: Therm-a-Rest NeoAir XLite NXT or Therm-a-Rest NeoAir XTherm NXT?
On the official Regular pages we fetched November 10, 2026, both pads share a 72 × 20 × 3 in outline and a WingLock valve. The XLite NXT is the official lighter, less expensive pad ($199.95, 13 oz, R-4.5, 30D on both sides). The XTherm NXT is the official warmer, tougher-bottom pad ($229.95, 15.5 oz, R-7.3, 70D bottom). We have not slept on either pad. Official “4-season ready” language on the XLite is not the same as CleverHiker’s winter recommendation, which points to the XTherm. Do not compare these Regular figures with a MAX, Regular Wide, or the Tensor All-Season as if they were the same SKU.
Choose Therm-a-Rest NeoAir XLite NXT if…
- You want the official 13 oz Regular weight and $199.95 price
- An official R-value of 4.5 is enough for the trips you actually take
- You are comparing Regular to Regular, not shopping the MAX rectangle
Choose Therm-a-Rest NeoAir XTherm NXT if…
- You want the official 7.3 R-value and 70D bottom at 15.5 oz official Regular weight
- You will accept $229.95, and you will note reviewers measured 16 oz
- You want a dedicated official cold-weather NeoAir rather than the official “4-season ready” XLite claim
Official “4-season ready” is not the same as a reviewer’s winter pick
The official XLite page we fetched November 10, 2026, says the 4.5 R-value is “good for year-round conditions” and calls the Regular pad “4-season ready.” The official XTherm page lists a 7.3 R-value and describes the pad for alpinists, mountaineers, and extreme cold. Both official pages discuss ASTM F3340-18 as the R-value standard. CleverHiker, last updated September 21, 2026, still treats the XLite as a three-season pad and would not choose it as a standalone pad for genuinely cold winter camping, preferring the XTherm’s 7.3 R-value over snow or frozen ground. We report that disagreement. We have not slept on either pad, and we do not invent a temperature rating from an R-value.
Who should skip both of these Regular NXT pads?
- Shoppers comparing the XLite with the NEMO Tensor All-Season. That is a different official comparison, already on another page.
- Anyone mixing Regular, Regular Wide, Large, or MAX weights in one table. Official XLite Regular is 13 oz; official XTherm Regular is 15.5 oz. Official Wide and Large figures are higher.
- People who want a rectangular, side-railed, or much thicker comfort pad. Official NXT Regular pads are tapered 72 × 20 × 3 in mummy outlines.
- Campers who only need a foam pad for mild nights. See our foam-versus-inflatable page.

A foam pad cannot go flat and asks you to carry bulk. An inflatable pack smaller and sleeps thicker, and it can leak. The official R-values in this guide are far apart, so this is not a warmth tie.
