Klymit Inertia X Frame

sleeping pad

The Inertia X Frame sleeping pad has been one of the most fun gear reviews that I have done. Everywhere I have taken this pad people have looked at it and wondered what is was and then if it worked. I have had a dozen or so people try it out for themselves and tell me what they think. I have also slept on it many times to see how comfortable it really is. I have yet to see someone that was not impressed by what the saw and felt.

First, to get started on some basic information about this pad. It is the lightest inflatable sleeping pad that I have seen, weighing only 9.1 ounces. (10.1 ounces if you include the dry air pump.) The pad also rolls down to the size of a can of soda.

This is all achieved by a process called body mapping. Body mapping gives the support and comfort in all the key pressureinside a tent zones of the body, while eliminating unnecessary material to reduce weight and pack size. This unnecessary material is Klymit's patent pending loft pocket technology. The cut out regions of the pad are what they call "loft pockets." The loft pockets help the insulation on the bottom of sleeping bags to maintain loft and warmth beneath your body, where it would normally be compacted.

All that said, the real question is does it work and is it worth sleeping on. The answer is yes to both questions. The pad is easy to inflate by blowing just a few time and then topping it off with the dry air pump. I found it quite easy to zero in on just the right pressure using the pump. After trying out the pad and feeling that it was supportive, I was excited to give it a try. I was skeptical though that the pad would only feel good while laying on your back. I was a little concerned that I might not have a great night sleep on this pad, as I normoally don't sleep on my back. I was quite impressed though at how the pad supported me while on my sides or stomach, as well. I slept good the first night and even better the second. Klymit has figured it out.

Are there sleeping pads out there that are more comfortable? Yes. But are there any pads that weigh this much, pack down this small and feel this great? Not that I know of. The biggest complaint that I got from people who laid down on this pad and for myself, was the width of this pad. As you can see in the picture below this pad is a couple inches narrower than some other sleeping pads. This is not a self-inflating pad either, so if that is what you are looking for this is not going to work. Sleeping pads

This is a great pad for anyone who is trying to save weigh but still have some comfort. I think this pad will work great for bicycle touring where every inch of space counts. Go and check this pad out and test it for yourself, I think you will be surprised at how comfortable it is.
