    Filling your mattress just got easier.

    The featherweight Therm-a-Rest AirTrap Pump Kit converts any air-tight bag into an efficient, quick-inflating pump. Pierce one of the included plastic bags, a garbage liner, or a plastic grocery bag with the tip and attach the valve coupler. Then, all you have to do is capture air in the open end of the bag, roll it down, and force all of that air into your mattress. You can even use a stuff sack to create a permanent pump system.

    light weight

    • Familiarity: I've put it through the wringer

    its light and it works with virtually any plastic bag it is a dream to use and after hiking all day long you dont want to blow up that therm-a-rest with just your lungs. this is that fix.

    Negligible weight. Essential functionality

      The key benefit of this valve is not in the convenience it provides (although that's nice too), but in the fact that it pushes AIR into your pad, and not your BREATH. Before using this valve, I had gotten used to the fact that my neoair would lose its firmness in the middle of the night. First time I used this valve in the backcountry, that didn't happen. I don't know the scientific explanation for it, but it works. And it weighs nothing. On the downside, I've already destroyed the included plastic bag, but that's easily replaceable so it doesn't matter.

      When you inflate by mouth, you are filling the pad with "hot" air. Because temperature affects pressure, as that "hot" air cools, the pressure in the pad goes down. This is why I believe I've seen many reviews on the NeoAir claiming that it seems to "loose air" over night.

      Except... that when I got my NeoAir, it was used for several years by blowing it up with my own breath and I noticed no significant volume contraction overnight. Starting last year, probably year 6 or 7, it did start losing volume to the point where I would wake up with a hip or shoulder poking into the ground.
      I have an engineering friend 🤓 who did the calculation on temperature and volume. He came to the conclusion that the volume difference from hot breath to cool air should not be so significant and I could confirm that empirically with the first few years of use.

      Neo Air Pump Kit, thumbs up!!

        It's the best $9.95 I've spent in a long time. Simply install the nozzle in the supplied plastic bag (takes all of 30 seconds) and it's ready to use. At the end of a long day, instead of the normal 25-30 breaths of air, that at times left me nearly dizzy to fill my NeoAir XLite pad, several bag fulls of air and virtually no effort easily inflated it. It's very light weight and I simply roll it up with the pad to carry it. Highly recommend it.

        We have 2 thermarest pads & 1 Klymit pad. Do you know if it works on Klymit pads? (I have the Klymit Insulated Static V). Thanks!

        Can it be use on the nemo astro air...

        Can it be use on the nemo astro air mattress??

        Will this work on a exped mattress?

        Will this work on a exped mattress?

        They use a different valve. But you can use the Big Agnes pumphouse which doesn't cost much more and quadruples as a drysack, pillow, campshower, water carrier.

        Exped also offers a pillow pump.
