I'm in the military, so I'm partial to hard cases (ie. Pelican, Hardigg) as that's what we use to transport our equipment. So when I went looking for a case for my tobacco products, that's the kind I looked for. If you want to go this route, may I suggest the Herf-a-dor from Humicare.
I love the fact that it is rugged unit, I can throw it in my pack and not worry about anything getting damaged. It's large enough to carry all my essential items- I can transport 4 eGo
batteries, 2 ProVari's, 4 Clearomizers, 1 Pro-V cartomator, 12 6 oz bottles of
juice, eGo battery charger, and still have room for stuff. It comes with foam, which I custom cut to better organize my gear. Link below, recommend the x15 or x40 size. If interested, these can be had cheaper on different websites, PM me if interested.
