I really like the Therm-a-Rest NeoAir mattresses: they are not only warm but very comfortable for my back.
You can blow them up with their air pump, which uses batteries instead of a USB adapter. 🙁
But you can as well use their pump bag, which 1) falls often off the valve when pumping and 2) can’t be used as a dry bag because of the hole.
The solution: buy the pump bag schnozel UL M from Exped and increase the inner diameter. You will still be able to use it for Exped mattresses, but as well for the NeoAir.
And because the Exped bag can be closed, you have as well a water tight bag for clothes.
Best of two worlds?
