I served in the Marine Corps for over 6 years and wore regular corsets attached to your socks. Now that I'm a Florida Police Officer, I've found these shirt holders that are not only easy to put on and take off and adjust. They fit perfectly under my duty belt. These are definitely game-changing and I would recommend them to all my buddies who are still in the Corps and to any LEO and security personnel who want to look stylish without those pesky old-school shirts. I love this product and will buy again when it needs to be replaced.
