Klymit X Frame Review: Lightweight Sleeping Pad for #backpacking & #travel #ttot

Are you looking for a lightweight sleeping pad for backpacking?

The problem with most sleeping pads I’ve used is they’re just too bulky to carry when travelling. Foam sleeping pad can be picked up ridiculously cheap at any discount shop, but they just take up too much space when rolled up.

It may not be an issue when trekking across the backend of rural Tasmania, but when you’re lugging an oversized backpack on the London underground at rush hour, then you start to question every extra item packed.

I don’t want to be stuck carrying something around that I might not use for the next couple of days or even weeks.

Lightweight Sleeping Pad for Backpacking

Enter the Klymit Inertia X Frame – possibly the lightest compressible full sized sleeping pad available to buy.

Lightweight Sleeping Pad for Backpacking

I first came across the Klymit Inertia X Frame Ultralight Backpacking Pad a few years back while looking around an outdoor store in Australia. My first thoughts were something like “what’s this?” which pretty much is still the reaction I get from others when its whipped it out today….

The Inertia X Frame ultralight pad is extremely light, compact, and has to be the funkiest lightweight sleeping pad for backpacking that I’ve come across.

It’s claimed to be the world’s lightest travel pad and only weighs a tiny 255g. Fully inflated it takes about the same space as a can of fizzy drink. It can easy fit in your travel pack or jacket pocket when rolled up.

Designed with body mapping research, the pad offers support and comfort in all the key pressure zones, while eliminating unnecessary material to reduce weight and size.

Advertised for three season use, the Inertia X Frame only takes a few breaths to inflate.

The firmness of the mat is adjustable by the hand air pump. This will allow you to inflate it to a high pressure compared to ordinary mouth inflatable pads.

Klymit X Frame Review: Lightweight Sleeping Pad for #backpacking & #travel #ttot

After months of consideration and a series of camping trips, in July 2014 I finally bought the Recon version of the Inertia X-Frame from Amazon.

For something with so little material, I wasn’t expecting much in return from the comfort department.

Yet I was pleasantly surprised by just how comfortable the pad was to sleep on.

The sleeping pad can become extremely firm if you prefer it that way. After some experimenting, I found its best to inflate the mat all the way by mouth and then use the hand pump to top it up as needed through the night .

The X-Frame is designed for back sleepers, but even with the space saving gaps, I found it can still be possible to sleep in the side position. Ok, it’s not the most comfortable position – but still possible.

Comfortable or not, using a lightweight sleeping pad for backpacking does have some some negatives.

As an active night sleeper, i.e., someone who turns a lot, I found myself walking up half on the pad and half off. Just imagine trying to stay on one of those blow-up beds while foating in the swimming pool.

Eventually I found the best solution is to zip my sleeping bag up all the way with the X frame inside. That way the X Frame stays close to you at all times.

2016 Update –

Two years have passed and wow, yes I’m still using the Klymit X-Frame.

For the past 730+ days, the Klymit pad has been used for camping, Couchsurfing, and even a spot of airport sleeping.

Those looking for a lightweight sleeping pad for backpacking will struggle to find something that can beat the size of the Klymit X Frame.

I love my travel gear and haven’t seen anything come close to this size.

There’s no doubt the Klymit X Frame is extremely lightweight and compact, but there’s certainly bigger and comfier travel pad available to buy.

On a good day I’m around 5′ 11″ in height, and although the Klymit X Frame is a great fit for me, I’m sure that someone who is taller would find the pad restrictive.

As previously mentioned it’s perfect suited for people who sleep on their backs and don’t move around much at night. The downside for a sleeping pad that’s only 18″ wide is those who are a larger build would have issues staying on the pad for a long period for time.

Also warm and hot climates suits the pad fine, but for cooler weather or sleeping on tiled floors, an additional insulator is a must.

For someone who travels regularly but only needs a lightweight sleeping pad for backpacking occasionally, the Inertia X Frame offers the perfect solution. Light, compact, and doesn’t take up much space –  but is always there if you need it.

10/10 for the innovative and the minimalistic design but at some sacrifice to comfort.

Check the links below for pricing:

The next smallest and lightweight sleeping pad for backpacking that I found is the Sea to Summit Ultralight, which is roughly about twice the size of the X Frame.

    This looks quite light and convenient to carry. I noticed the design of the pad looks it is made specifically keeping in mind the contours and frame of the body. So I am guessing it would be a good base for support and comfortable sleeping position.

      It does the job Vyjay and I haven’t had any issue yet. The body mapping tends to work as my back feels better when I’ve slept on the Klymit X Frame

    Great review Barry, I know how important space is when backpacking so it’s good you’ve found something super lightweight that still works. The tip of putting it in your sleeping bag is a clever one too.

    • Barry Sproston

      Cheers David. Yeah the sleeping pad is small enough to fit inside the sleeping bag and tends to work.

    Wow brilliant! this is exactly what we need for our next camping trip! Thanks for sharing

    Posted October 22, 2016

    Nice and honest review. It’s great that after all this time you would still recommend it and still use it. Definitely keep it mind for future trips, thanks for sharing.

      No problem Lisa. If I like a product then I will recommend it.

    What an innovative idea, this is brilliant! I loved your review as well, fully informative with the pros and cons. I am a wiggly side sleeper and only 5″2 so unsure how it would work for me but I thought I would click on the link for cost – if it was cheaper than the price showing on Amazon, I may have purchased it because I do think this is a fantastic idea. Unfortunately the price tag for an “idea” at this stage isn’t for me. Aside from my personal opinion on the product, I will reiterate that your review was just perfect so thank you for taking the time to fully test and share your findings with us!

    • Barry Sproston

      Cheers for the feedback and some valid points Angie. My girlfriend has used it a few times, and she’s 5″4 so I would imagine 5″2 would be ok on the pad too.

      The one thing I didn’t cover much in the review is the price, and I will agree that the Klymit X Frame pricing isn’t cheap. I’m told that I can be a typical guy when it comes to buying things and don’t tend to see the price much. The reason is if the product can provide me with value and is durable enough to withstand my travels, the price isn’t important (within reason) to me.

    Interesting product and an informative review. I am also someone that turns around quite a lot in my sleep but your solution makes a lot of sense and seems like it did the trick. I could have done with it on my 6 week camping trip around USA!

    • Barry Sproston
      Posted November 24, 2016

      Thanks Lexx. I always travel with it in my pack these days as I never know when I will need it next. Camping in the USA sounds fun.

    This is actually exactly what we’ve been looking for to add to our camping supplies. We don’t have pads for our sleeping bags, so sleeping has been rather uncomfortable… This pad sounds amazing and durable, definitely something we’d been interested in taking a look at. Thanks for the informative and helpful review, Barry!

    • Barry Sproston
      Posted November 24, 2016

      No problem Anna. I have used it for camping plenty of times in the past 2 years and the X-Frame has held up well. I’m sure there will be more comfortable pads out there but it’s certainly better than no sleeping pad.

    I didn’t even know these kind of things exist haha! I was tempted to get one when I read how light and compact these are, but then I realized I twist and turn all night and I almost never sleep on my back. I wonder if there is something similar made for the ones like me too? Thanks for sharing though! Always good to find out about new travel gear!

    • Barry Sproston
      Posted November 24, 2016

      I know what you mean Kreete as I turn a lot as well. I haven’t seen one as of yet but if I do I will let you know…

    Great review of the product, and that is an awesome product will save a lot of space too!!

      Yeah, its true that the Klymit X Frame saves lots of space.

  • Kelly Turpin

    Wow, that is like crazy small! We may need something like that soon. I will keep these in mind. Great review thank you.

    This is really cool. Sometimes the mat can be half of the sleeping bag which takes loads of space in your backpack, not to mention the weight. Thank you sharing this, I might give it a try for upcoming trips.

    • Barry Sproston
      Posted November 24, 2016

      There’s nothing worse than wasting backpack space. If I can go smaller and lighter then I will.

    This is so cool. I have been looking for a lightweight travel mat for a long time. This looks like it will do the job for my upcoming trip around Europe.

      To be honest its that light I hardly notice I’m carrying it 🙂
