Thanks to eric.hermann for starting this poll! We've contacted the vendor on your behalf and they've made the Therm-a-Rest NeoAir XTherm Sleeping Pads available.
i love the xtherm just for the r-value weight to insulation ratio is worth it. Xtra 4 oz for the insulation I will gladly pay it and tote it on the PCT. I love my Xlite but i noticed on the AT it had cold spot early in the trail where temps dropped below 30. And not to forget the large has an extra 5" not seem like much to most hikers but it makes a difference for just keeping those hands or elbows from falling to the ground and getting cold .
The Therm-a-rest XTherm is probably the best warmth/weight ratio of any pad. The Max version is compatible with double sleeping bags, and gives you a bit more wiggle room (which I personally like).
