Hi,
Just thought I would let you know that I just finished a 7 day hike on the "West Coast Trail" and I was using the "Klymit Inertia X frame" for my sleeping pad. It was everything that I had hoped for, small, compact, light and very, very comfortable. The set up and adjustments (more / less air) were quick and easy.

Hello Chuk,
By chance do you know how much yours weighs?
And did you sleep on your back the whole time?
Did you use a sleeping bag or quilt?
Thanx!

Hi BarryP,
It weighs .682 lb.
I slept on my back and sides and was using a down sleeping bag. Some nights I pumped it up hard and others soft,I was skeptical when I bought it but will be using this as my main sleeping pad.
I was very comfortable sleeping on it. Also what a space saver!

my concern with the x-frame is not support it is insulation. With those big open gaps it doesn't seem like it wouldn't insulate you very much from the ground. It also seems pretty incompatible with a quilt. Perhaps with a full bag the down would fill in the sections giving you adequate insulation.

How would feel about using the pad at elevation or during shoulder seasons?

BZH,
Good point!
I would use this pad in the shoulder season with a down bag but would definitely not use this with a quilt.We set up camp on wet sand as we had heavy fog for three days.

I did not notice any poor insulation during our trip but the Temperature would only drop to about 48-51 degrees at night.

Maybe someone can give us some feedback about the insulation??

Hey guys, Nate Alder here, Founder and CEO of Klymit. I came across the thread here and thought I might try to share some insight behind this.

Surprisingly, the Loft Pockets in our pads do exactly what they say, they create pockets of loft. The Loft Pockets actually are the warmest part of the pad. Hard to believe at first until you test it out for yourself, but we have personally tested it to minus -15 degrees F last winter, and a couple Special Ops teams we work with have tested it to minus -60 F. The Loft pockets simple allow your sleeping bag insulation to maintain its Clo value (insulation value) by not compressing the insulation. Thus, the insulating value of the Inertia X Frame is totally concurrent with the thermal rating of the sleeping bag you use with it. That’s what makes it so thermally efficient, it adapts to all kinds of temperature ranges as you bring the right sleeping bag for your trip. I have received a few calls from troops in the Middle East that use our pads from low altitude in Iraq where it is hot talking about how they use just a poncho on top of them at night, and the Loft Pockets create high ventilation points for them to stay cool off the hot desert ground, but when they go in to high altitude in Afghanistan the pad keeps them very warm when used with a sleeping bag.

Here is a short video showing how the Loft Pockets work: http://youtu.be/VgWDvpnrPHk

That being said, a quilt on a very cold night would probably not be best by itself with the Inertia X Frame, but the holes provide about a 2.8 R-value by themselves with zero sleeping bag. I know several people have used it with a quilt on the AT with great reviews, but I have not personally tested it that way myself yet.

I hope this helps

It's always good to hear from the manufacturer! Thank you. Nate, for responding!

I've read a few reviews from people who state that they basically fall through the holes. In other words, not everyone's body fits the pad! This is probably something you want to try out on the floor before buying. IMHO, that's a good idea for any sleeping pad.

Hey Mouse,

You're right, not everyone fits perfectly on the pad. The Inertia X Frame is our most popular pad, and fits most people, but I am a bit of a mutant I guess as the body mapping fits most people, but not me perfectly. That is one of the reasons why we created the Inertia XL with a more universal body map design. It is my favorite, but the pad I take with me all depends on the trip. If I am going for more light weight and warmth I go with the Inertia X Frame, for more comfort I use the XL, and I almost always have the X-Lite with me especially when I travel as it has provided a much more comfortable surface for long delays or flight cancellations than trying to twist my body around the benches with arm rests.

You're absolutely right though Mouse, to choose the best pad for you it is always best to try it out first before you get deep in to the back country

We are just getting started in the pad market, so we only have 3 models right now, but as we grow we will come out with more and more options that cover more body styles, so stay tuned
