I live in a climate that's cold most of the year. We only get about 2 months of warm to hot weather. It's not fun putting a freezing cold metal thing in your hands, and even less fun to put it between your lips. Does anyone make rubber or hard leather battery cases and drip tips? I've found photos of some nice leather holsters online, of course, but none of have links of where to get them. So where do you get them?
