If it covers your weapon with your arms extended out to your side it is legal whether it is a shirt,vest,jacket or coat.I think a shirt is a little on the flimsy side as I wore one for a while and would always get a handful of it as well as the gun when drawing from the holster.Look around on ebay for a used 5.11 vest or check out www.pistolpacking.com as they have a nice vest without all the pockets of the 5.11.I wish you luck,Ken
