Our 2nd generation t-shirt carrier upgrades the previous version.  Changes that were made results in a better fit, feel, and ability to hold armor more efficiently.  Reinforcing the pocket edges with a more stout material helps keep your protection where it should be!  Sizing runs small, please refer to the sizing chart for the best fit. A good general rule is to buy 1 size larger than what you normally would wear as these shirts run small and are designed to fit tightly and hug your body ! (No returns. All sales final on t-shirt carriers.)
