Klymit Inertia O-Zone Sleeping Mat - Review


Daniel Gangur takes some amazing photos of our great Country. On a regular basis, we'll send him some gear to field test on his expeditions and give us his feedback on what works and what doesn't.

Here's what Daniel had to say about the Klymit Inertia O-Zone Sleeping mat.....


The Inertia O Zone is a lightweight sleeping pad designed to provide padding where needed while shedding weight by eliminating padding where it’s not, the empty “pockets” act as a space for your sleeping bag to loft beneath you maximising the thermal performance. It has a built in pillow, can be using in and out side your sleeping bag, packs small and takes only a few breaths to inflate.

Here’s the specs,

RRP $159 AU
Weight 12.2 oz / 354 g
Dimensions 72″ x 21.5″ x 1.75″ / 183 cm x 54.6 cm x 4.4 cm
Inflation 4-7 Breaths
Pack Size 3.5″ x 6″ / 8.9 cm x 15.2 cm
Fabric 30D Top / 75D Bottom Polyester

“Loft Pockets” eliminating padding where not needed whilst providing space for your sleeping pad to loft, smart design!

I have been using the Klymit Inertia O Zone for about 6months now for bike packing, general camping and photography adventures, so what do I like/dont like.


  • Comfortable
  • Lightweight
  • Packs small
  • Super quick to inflate
  • Loft pockets seem to work well
  • Comfortable yep mentioned twice because its worth mentioning again
  • Looks cool

Don’t like,

  • Has a tendency to slip around on the tent floor

Yep it’s almost all good!


I’m 176cm tall so the pad at 183cm is plenty long enough for me with my head on the pillow you can see that there is still a bit of room at the foot end.

The pillow, its a tad bit small in my opinion obviously to save weight. I do like the shape as your head stays central in and doesn’t slip, I’ve been throwing a t-shirt or something on top just for a little bit more height.

There is one of these inflation valves on both the pillow and the body of the pad. They are easy to use, allow quick inflation and allow plenty of air to escape to deflate the pad. They had a “positive” lock, have not had one open up while sleeping.

The Klymit Inertia Ozone packed up into its small storage bag, as you can see it doesn’t take up a lot of space and at 354g doesn’t weigh much either, I’ve added my phone, a Sony Xperia to this pic to give scale. The pad is also quite stuffable so you can squeeze it in around other gear.

I usually have this pad in my Oveja Negra saddle bag along with my sleeping bag, jacket, some spare clothes to sleep in, a power bank, dinner and what ever else I might need at the end of the day. You also get a small repair kit that sits in the top of the storage bag so its with you if you need it.

Inflation, decided to add a video here to show you how quickly the pad is to inflate.

Did I mention how cool this looks! Something a little different I guess, unfortunately I haven’t had a chance to test the loft pockets in really cold conditions, but I haven’t had a problem with warmth yet. I’m about to head off on a Mountain Bike ride in some of Australia’s highest country so will probably get a chance to update you guys on this shortly.


So far I’ve been pretty impressed with this sleeping pad, it takes up a tiny amount of space in my kit, so important on the bike, I can easily pack it in my saddlebag, in with my tent in a handlebar roll or even in my camelback. It is comfortable, I was pretty skeptical about how comfortable it would be given there isn’t a lot of padding but its been great, actually at the end of a big ride its a really welcome bit of comfort, so is the ability to blow it up with little effort. Honestly the only thing that I haven’t liked has been the pads tendency to slip a bit in the tent as you move in your sleep, those that use the pad in their sleeping bag will not have this problem, It really hasn’t been too big a problem its just worth mentioning here in this review.

All up I think its a great option for lightweight bike packing, hiking, kayaking trips etc where space and weight is at a premium, but I’ve also found it comfortable enough for general camping. Personally I won’t be looking for a new sleeping pad any time soon as this really fits my needs.
