Thunderwear and SmartCarry etc....somehow I just don't like a gun hanging over my family jewels. I would think the better idea is the compression shirt with built in holster. USCCA holster guide talks about this idea (they cover SmartCarry too) so something like

http://www.abetterholster.com/ . You could also with drawstring pants look at a ClipDraw potentially. I haven't done any of these and don't actively jog anymore (purely into interval training now). The downside of having the gun up under your armpit is you probably have another tshirt over this that you are going to have to get up and under. For me, I figure if I was back out running again I would be going more with the tigerlight or my kimber pepper spray unit as I am more worried about dogs/bears/cougars than humans (I can outrun most of those).
