The primary thing I look for in concealment is to carry in such a way that you do not look out of place. Where I live, anyone wearing a vest in 100 degree heat, with humidity to match, is darn sure going to look out of place. The only ones wearing a fanny pack are dudes and tourists. What may be acceptable in NY, doesn't always fly in the south. Glad your vest works for you in your part of the world. Down here it's pocket holsters, belly bands, and ankle rigs, and of course the IWB with an untucked shirt. I think that is the point jhm was trying to make. Nice vest though!
