Great under shirt for patrol - 5.11 Tactical Tight Crew S/S Shirt - Men's

I have tried other compression shirts and believe that the 5.11 compression shirts are the best for patrol when wearing a concealable vest. These shirts do not bind under the vest like other loose fit shirts and do not ride up, for those who know what I am talking about, it is a terrible thing when it happens because then you have to take off all of your gear to re-tuck your shirt. They seem very durable and will last for some time. The only negative I have found is that they are expensive and that 5.11 does not offer a sleeveless version like Underarmor does.
