Just curious how you guys carry around all of your vaping gear? I've already figured out that carrying a box and tank requires a little more care than a pack of smokes and a lighter. And most weekdays, I haven't had the need to bring out any more than that. But on the weekends, whether I'm out hiking/fishing, or cruising through the city with my buddies, I have noticed a definite need to have a couple of items on hand. What I would like to do is be able to carry a spare 18650 battery and a loaded tank for those evenings bar hopping or for days at the park/beach. I'm hoping to find a wallet type deal that I can slip in my back pocket. Any ideas gents?
