Small on size and weight, big on performance! Klymit…

Rating: rated 2 of 5 stars
Source: bought it new
Price Paid: $90


Small on size and weight, big on performance! Klymit successfully set out to create air mattress comfort with the minimal weight penalty that is more typical with closed cell foam pads.


  • Minimalist small size when packed
  • Ultralight for an air mattress at 6.9 ounces
  • Only two breaths to inflate — Dry Air Pump not needed
  • 3/4 length is fine
  • Works inside your sleeping bag
  • Klymit "body mapping" design seems very supportive and comfortable


  • There is a significant comfort issue — see details


Klymit Inertia X-Lite Recon Inflated


Klymit Inertia X-Lite Recon on top of the pack.  Man that is small.

I took a group of Scouts on a winter campout this weekend, and thought I'd give my new Klymit Inertia X-Lite Recon a try. This would be a nicely controlled test of its performance as I'd be in a lightly heated alpine cabin where I'd sleep in an unpadded bunk. This would give me a chance to see how the pad works without the variables of rocks or roots under my back.

First, the good:

  • Minimalist size and weight — This really does pack down small and weighs in at only 6.9 ounces. In an effort to follow "Minimalist" and "Ultralight" hiking theory, I've been trying to get my gear smaller and lighter. The Inertia X-Lite Recon certainly gets top marks in this respect.
  • As the manufacturer advertises, it takes less than two breaths to fill the pad. Nice. I'd also like to add, there really is no need for the Dry Air Pump. In some ways, I think it's useless and it really just takes up space.  YMMV.
  • The 3/4 length works from a sleeping pad point of view. From a thermal point of view, I can't be sure as I was also sleeping on a full-length 1/2" thick Evopad which has always kept me warm even in sub-20°F weather.
  • I used the air pad inside my sleeping bag and it seemed to work great that way... at least as I went to bed it felt good.

Now, the bad:

  • As I went to sleep, I was sure I'd be rating this pad as a 5 star. I was so comfortable and well supported.  I thought that the body mapping was wonderful from a spinal-support point of view. A few hours later I woke up with a terrible feeling in my spine.  It didn't occur to me that the pad was the issue, so I re-adjusted and tried to get back to sleep. Hours of this went by as I continually re-adjusted.  Finally I pulled the pad out of my sleeping bag. This quickly fixed the issue and I got a little sleep.

I am not giving up on the pad. I'm going to try it again and see if the bad experience was an anomaly. If there's an improvement, I'll gladly come back and alter my review.  For now, I have to say the pad is unusable and I don't know why. I very much hope I'm wrong.
