Worried about snapping connectors etc., I bought a couple of cheap cigar tubes. Amazon has a million of them. Note the "gauge" of cigar it will hold, divide by 64, and that is the width of
mod in inches it will hold. Makes even less-pocketable
mod/
tank combos a little more pocketable.
When a pocket is not required, pencil cases are great (mentioned earlier in this thread). Also check amazon for "EMT pouch" and "tactical pouch" for larger options. Insanely durable solutions, and they don't look like a man-purse.
