Argon Update: Klymit Inertia X-Frame Sleeping Pad

This is not an Argon or insulated pad. It is a fantastic 3-season pad that is a miraculous 9.1 oz. Using body mapping technology, it supplies air filled tubes at pressure points fulfilling 3 main advantages: a) creating voids to lighten overall weight, b) allowing space for sleeping bag's loft to expand, thereby increasing warmth, and c) decreasing the space to which air escapes when the body's pressure points (hips, shoulders, head) contact the pad. This gem is a better buy than competing pads, is plenty tough and includes an optional hand pump to fine tune your preferred firmness. I own several matresses of different makes. For backpacking, this is primo.

I bought an X Frame to take on the Overland track, a 7 day wilderness trek in Tasmania. I wanted a comfortable lightweight option to convince my wife to do the trip.
While you can't argue with the X Frame's exceptionally light weight and compact size when packed I would say there are a couple of issues worth considering.
I'm 5'10" and I line up OK with the head, shoulder, hip and foot padding. My wife is 5'4" so she didn't line up that well. This was enough of an issue that she asked to swap with my self-inflating mat halfway through the trip.
Apparently 70% of us sleep on our sides. I do, and I bend my knees when I do, and my legs didn't line up with the foot rest section when I did this. This wasn't really a big deal as the 4 tubes provide adequate rest for your legs even when bent. It is the case though that I woke up each time I rolled over because I needed to find the right spot to lie on. The X Frame is also slippery and fairly narrow: adding to the need to wake up each time you reposition in order to get on it comfortably.
The concept that the cut out sections allow your sleeping bag to loft and provide better warmth is OK but one night, while sleeping in a hut, my hydration bladder, which I had beside me, leaked (thanks Kathmandu...!) and woke up lying in a pool of water, my sleeping bag completely soaked. This would have been less of a drama if I had been on a conventional mat. The fact that the X Frame allows your sleeping bag to have direct contact with the floor, especially if you were in a tent in freezing or wet conditions is an issue. Having to take a second mat to put under the X Frame to solve this rather defeats the purpose.
I make myself a pillow by stuffing my sleeping bag cover with clothes. Most people do. With the X Frame you have to get your pillow to stay on the 'head support' section, another slippery task. I think the head support section could be omitted.
Overall I felt that the X Frame would be good for quite extreme conditions but that another model that was slightly wider, that had larger 'support' sections and smaller 'cutout' sections and was non-skid on one side would be great and would sacrifice very little of the great advantages of micro weight and tiny pack size of the current model.

BTW It isn't filled with argon gas.

Smart but how durable is it?

maybe too much like a skeleton.
