Fucking Combustion (mostly) Since February 2017
This is what I use. Its not smell proof but it does a pretty good job. It also works with the Nomad 1. I found it on Amazon but its currently unavailable. Not sure when that became the case or if its a temporary situation.

I have that exact same case that I bought for my Nomad I as well. It's the perfect size.
