Depends how long I am going to be out.
If I am going to be out for a while, then I have a leather holster that holds the GLV and a 15ml bottle of juice. Extra batteries are kept in a battery holder that stores in the ammo pouch on my holster.
If its going to be a quick run out, then usually I take a freshly filled carto, and I use the ammo pouch on the front of my holster to hold the GLV, also with fresh batteries.
Most badass thing I have seen in a long time
I just ordered this today, it's not very McGuiver but I'm new to all this JoyeTech eGo semi-soft black carrying case - Genuine JoyeTech!
