Hey, New members, welcome to TFL. I hope we can help you learn.
Perhaps if you were to sew on one or more decorative patches (that would look good on green). I know several people that carry pistols in "fanny packs" that have done that with the packs. There is something about a innocuous design on something that defuses any thought of a possible concealed weapon.
