I just thought I'd throw some props out for the Armored Humidor. A waterproof Pelican case with a dehumidifier packet that works for 6 months or so with no screwing around.

Mine holds 8 cigars and has been rafting, Fishing, Hunting and banged around the world a couple of times.

They come bigger but i think the size I have is perfect.
