R 4.5 for 370 g, the benchmark three-season pad. The price, the 30D fabric and a narrow mummy cut are what you pay for that ratio.
Therm-a-Rest rates the XLite NXT at R 4.5 and cites the ASTM F3340 standard, at 370 g and 7.6 cm thick in the Regular size. That ratio is why it sits at the top of most three-season lists. It is just under the R 4.8 mat that ISO sleeping bag ratings are measured on, so a bag's comfort figure roughly holds on it.

The NXT version claims to be 83 percent quieter than the previous XLite, whose crinkle was its best-known complaint. It packs to 23 x 10 cm in a stuff sack, which shares a seatpack with a quilt rather than taking a bar roll of its own. The WingLock valve inflates with the included pump sack and deflates quickly.
The trade-offs are physical. Both faces are 30D fabric, so it wants a groundsheet on gravel or thorny ground, and the tapered mummy cut is narrow for restless sleepers. Owner reports on Amazon US include seam leaks inside the first year, complaints that it is too narrow and too loud, and a slippery surface that lets a sleeping bag slide off. At about $200 list, it is a premium buy.
The Verdict
The pad the others are measured against for warmth per gram. Narrow, slippery and expensive, and still the one to beat on a bike.
