Klymit Inertia O Zone
While I enjoy this product and find it comfortable, there are compromises that must be made to meet the low weight of the product.
Best for summer, spring, fall weather.
Best for those willing to make sacrifices to save weight.
- Easy to inflate
- Quality materials
- Desgined to go inside your bag, reducing falling off
- Vent locations
- Learning curve on deflating/rolling back up
- Learning curve on finding your comfort balance
- Side sleeping comfort — pillow hight challenges
I find myself enjoying this product the more I use it, and I find myself finding challenges overcome as well. As I get more use to the way it works, the easier it is to use it.
I've put a few trips on this air mattress and find it sufficient to write a little about it.
I find it easy to blow up and get ready for bed. I don't like sleeping directly on it, if not wearing a base layer to bed. The time I used it with a base-layer, I found myself much more comfortable.
I use it in a Marmot 700+ down 32 degree bag. The trip conditions were snowing and temperature hovering around 30 degrees, I found the loft pockets worked as recommended by Klymit. There were some lofting challenges if I found myself rolling around too much, I could feel the air coming up from the ground, but then as the pockets recharged if you will with warm air, this issue went away.
A time that I used it with just boxers and no base layer, it was nightly temperatures hovering in the mid 50's. I found this not as comfortable and I am now looking at getting a liner and seeing how that would make it even better. It's just that you are laying directly on the materials and they aren't as comfortable as laying directly on say the sleeping bag.
If you are a back sleeper, this is great for you. I loved laying on my back and found that it cradled my 6' 185 lb frame just fine. it was a nice touch the pillow also articulated my head in such a way to make night breathing easier if that makes sense. This is something I sometimes struggle with in the confinements of a tent and often bring decongestants just so I can sleep while cooped up.
I do like to side sleep as well, I found this a little more challenging, with the pillow height just not quite high enough. I over came this by putting a few articles of clothing on it and that did the trick.
I have also tested this product on my stomach and found that surprisingly comfortable, even though I am not a stomach sleeper, I could see this working out, as long as you don't mind your arms under your head.
The challenges I didn't like so much were figuring out how to get all the air back out of it. I watched Klymit's videos on YouTube to really see the best method for getting it back down to soda can size.
I have had no issues with the few trips I have taken it on with punctures and don't see this being an issue. It holds air well through the nigh and was not too difficult (like some air mattresses) to figure out the vent locking valves to keep all your air in. Klmit has done a great job engineering the air valves.
I only wish they were somewhere else as I come across them sometimes in the night and have to maneuver around them.
Overall I am satisfied with the product. I find it to be a great balance of comfort, value and convenience. Something I am willing to continue to use and have not found anything that quite meets the mark on all three points.
Comfort: The great lofting and built in pillow, keeps you warm enough, off the ground enough and in a good position.
Value: Great price to materials and design. I anticipate getting a few years of good service out of it.
Convenience: The size is great at 13oz and smaller than a water bottle, it takes up very little room. It even has a built in storage pocket for a repair kit so in the event you are in the field you don't have to find it elsewhere.
