Resizing the Massdrop x Klymit Static V Ultralight Sleeping Pad

Resizing the Massdrop x Klymit Static V Ultralight Sleeping Pad

Greetings adventurers,

Last month I published an article entitled ‘Massdrop x Klymit ‘Static V Ultra Light‘ in which I took at look at the collaboration work between Massdrop and Klymit with the introduction of their new 20d fabric sleeping pad.

Towards the end of the article I made this statement:

I know some of you are going to be wondering about modifying the Massdrop x Klymit ‘Static V Ultra Light’. As some of us have – myself included – with other Klymit (and even TaR) sleeping pads, the Massdrop x Klymit ‘Static V Ultra Light’ is manufactured like all of the other Klymit sleeping pads, that is, with a heat pressure machine. This means that you will easily be able to cut down the Massdrop x Klymit ‘Static V Ultra Light’ from the standard 72″ length to something in the shorter range

I was asked if I would be willing to make a video showing how this is done.

It took me a bit of work, as the video shoot unfortunately turned into about 3.5 hours of total video, as I talked my way through every little step as I was recording. The total shoot time spanned three days of modifying the pad (and thus shooting video) with a one day delay due to my archaic iron not working and having to purchase a new one.

For the sake of everybody, I got the main video shortened down to about 40 minutes.

I realize that is still a very long video and I will not feel bad if anybody skips ahead to the good part, towards the end, but hopefully there will be something in the first 30 or so minutes that will interest some folks.


So a bit of background here… I have cut/resized and resealed over a dozen Klymit sleeping pads over the years. Klymit brought to market the “Inertia X Wave” after I bought and resized an “Inertia XL” and posted about it years ago. I have also cut and resized a few dozen different TaR NeoAir Xlite and XTherm pads. At one point I was buying XTherm’s and cutting them into pads+pillows for people on expeditions. I could get five or so pillows from each pad, or one shortened pad and two pillows. They were a bit tricky because of the extra layers and trying to get the air valve sealed, but it was fun while I did it.

Suffice to say, the entire process is a very simple task, that requires very little time or effort. The biggest thing it involves is getting over the fear of damaging your sleeping pad – and for some of them, a very expensive sleeping pad.

Based on looking at the video that I shoot and tracking the time, you can cut and reseal your sleeping pad in under 30 seconds – when it came down to it, it took me 24 seconds.

Really, it is a simple and fast process.

With the very low price tag Massdrop x Klymit Static V Ultra Light and the fact it is a 20d fabric, it provides those looking for a fairly light and short sleeping a pretty smart purchase.


Video Insights:

I have two videos that I have uploaded.

The first is a 40 minute video and the second is a 40 second video (yeah, I couldn’t help it lol.)

Watch the second/short one if you just want specs and to quickly see the process.

Watch the first one all the way through if you really want to know some of the thought process and gibberish talking as I go through all the different steps/process.

Within the first/longer video, I actually discover what I think is a really sweet cut pattern and length, at least for me. I do end up cutting it down to the 48″ mark, because that is the length everybody seems to want, but I really did like the first length/design pattern I came up with. It might be worth watching that if you do not want a straight-cut pad.

If you are interested in a 48″ only pad, watch the first/longer video and fast forward to the 32:00 mark.

Sadly some of the longer video is rather dark. Apologies for this. Was not exactly something I could go back and reshoot… once the pad was cut, it was kind of a done deal.



The full length pad: 352 grams / 12.42

The 48″ length pad: 208 grams / 7.3 ounces

So that makes a savings of 144 grams (5.08 ounces) by cutting the length from 72 inches down to 48 inches, a reduction of 24 inches, which works out to 6 grams per inch of cut fabric.


Here is the full length, 40 minute, video (1080p available):


Here is the very short, 40 second, video (1080p available):

I hope some of you find these videos to be useful.

  1. What a great write up and video John thanks for taking the time to explain how it’s done! I’ve always wanted to shorten pad, but never had the courage.

    Do you think that Therm-a-Rest EvoLite Sleeping Pad would work with the foam inside?

    Thanks again!


    1. Hey Derek,


      The EvoLite huh… as you may know it got included in my 2015 gear of the year award… but gotta say I have held off whacking it down in size.

      Simply put, I have been too scared of what would happen with the foam in there. Unlike all these other pads, the EvoLite remains my primary sleeping pad, so destroying it would seriously make me sad and probably cry :(

      While I really do not think it would mess up, I just have not had the guts to do it. I know it is just standard foam in there, but my lack of knowledge of what happens to the foam when you cut it is what has kept me from doing it. I have no idea if I need some kind of hot blade knife in order to cut/seal the foam, or if a pair of scissors is just going to be fine.

      Perhaps I will drop my contacts at TaR and ask them. If I hear back from them, I will report back. Heck, maybe I could get them to send me a EvoLite PLUS on special pricing, which I can than whack on to test all of this. That would be sweet.

      1. The review you did on the Evolite sleeping pad is why I bought the Evolite. I’m glad I did it’s the most comfortable sleeping pad I own by fare!

        I’m going to try and shorten the evolite and I will let you know how it goes, but after watch your video and reading more about the foam used I don’t see why it would be an issue shortening it.

        Thanks again for the fast reply and the feed back! Really enjoy all your revies!


        1. Sweet, let me know how it goes. I would love to see a photograph of the inside of the Evolite once you have cut it. Highly interested in seeing what the foam + baffles looks like. If you would be up for snapping a photo and emailing it to me, that would be very much appreciated! is my email address. So what length are you going to cut it down too? Did you go with the regular size or the large/25″ width? Have you seen the new TrailKing SV that is suppose to be out in January 2017? Thinking I might have to try one of them. And yeah, for its weight category, I truly do think the current Evolite is the most amazingly comfortable sleeping pad out there!

          1. I will definitely send you pictures of the inside! I bought the regular size pad and I’m not planning on cutting much off, because I want to make sure it works for me first. So going to start with 15″ and see how I like it!

            I will send you pictures this weekend! :-)

  2. Great post and great video. Thanks for sharing. I also own this sleeping pad (with the insulation) and so far each time I have used it I slept good and comfortable on it.

    Thanks for sharing
