Love this shirt! I am an LEO and spend 12 or more hours a day in a bulletproof vest. Anyone who wears one knows that it is almost impossible to not stink horribly by the time you take it off. I wore this shirt under my vest for 12 hours yesterday and when I got home I did not even have to change my shirt, no smell at all! Ordering more of these for everyday! Thanks for the great product!!!!
