I just got the Thermarest Xtherm MAX Regular. It's great, very comfortable, no issues with crinkling noise.

But there's one problem: it's incredibly difficult to put in the sleeve of my Big Agnes sleeping bag. (It's a Roxy Ann 15 down filled.)

Seems like the Xtherm is just a tiny bit too wide. This is odd, because my last pad (Exped Synmat UL 7 Medium) was the same listed dimensions, 72x20". The Xtherm is even supposed to be a little thinner, 2.5" for the Xtherm vs. 2.8" for the Synmat.

I have to really work to get it all the way in, the fit is extremely tight, and it takes a long time and is very annoying.

Anyone else run into this?
