Rejoice! New rectangular xtherm for 2015

Nice to see a rectangular version. Too late for me though as I chose two Exped Downmat UL7's over the XTherm last year to mate together, and therefore, shape was the deciding factor.

The real question: is it quieter?

I saw those on the Thermarest site earlier today when looking around… have been interested in some of the UL Downmats too, but after seeing this, I will wait. The TAR site though didn't seem to be clear on the pads… it looks like they are still carrying a mummy shape too, but only list one weight, so not sure for which shaped pad it is, although, I'll bet it's the mummy shaped.

Anyway, rvalue of 5.7, and a 50D bottom! I will hopefully pick one of these up this summer! :)

I would probably lean to the XTherm today if I was buying today just to avoid the hassle of having to inflate the Downmats, but they are wicked warm. I know they are supposed to be as warm, but I have a hard time believing that a pad with no "real" insulation gets an R value that high. The people I know who have the X Therm love it however. In my case, I needed to join two pads together at times so I wanted a rectangular pad.

It looks like Therm-a-rest has changed the bottom fabric from a 70D to a 50D. That was the same move they made on the super-durable ProLite model a couple of years ago, so I suppose it was inevitable.

It probably won't matter, so long as Cascade Designs maintains its stellar warranty. But I for one am glad I have the 70D bottom on my pad.

I posted a while back disgruntled that the inflated width was a few inches shorter than listed – had to go Long just to get something that felt wide enough. In the posted picture, the original XTherm is offset quite a bit to make it look like the rectangular XTherm is wider. If this is true, and that the rectangular model is going to be the same width, then poo on Thermarest. Poo.

Can anyone make a comparison between the previous Xtherm fabric and the 2015 fabric (described on the website as "a new, softer, textured no-slip fabric for better next-to-skin comfort and a quieter rest")?

It will be 50 grams heavier than the original. Does this shape make much difference?

here are the specs

Weight Regular : 490g – Large : 640g

If I end up getting a Xtherm Max, Lg, @ REI tomorrow I'll post a comparison. My wife has the 2014 Xtherm.

Gary (and anyone else who has used these in very cold weather — 0°F and below), are these mattresses adequate without any supplemental CCF?

Looks to me like the Max version is not in REI store… needs to be backordered from the website.

Yep no need for supplemental mats. But Neoairs have some serious competiotion with the new Exped mats in stock now. I may even get one and return the xtherm.
