After extensive testing we love these shirts. We're former military officers who think these highly functional shirts are outstanding. They retain military standards but have custom features you won't find in standard issue military shirts. They are a comfortable athletic fit, look sharp and are built for superior endurance and stain resistance.  Two niggling complaints: they're a bit expensive and delivery can be a bit slow; but these shirts are worth the wait.

Here are the features we like best:
[1] The hidden zipper mock button-up front allows for incredibly quick changes, easy ventilation during intense activity and fast access to vests and weapons.
[2] The chest pockets have velcro closures to keep the flaps flush, contents secure AND both have pen slots that allow you to carry pens, pencils, sunglasses and penlights at the ready.
[3] The huge, hidden, vertical-zippered pockets behind the chest pockets that are large enough to hold a folded map, notebook, head set, cell phone, snack bar, paperback book, etc.
[4] The hidden, button-downed collar stays that keep the collar looking sharp without effort.
[5] The fabric these shirts are made of is top grade. The shirts stay crisp, keep their shape and look sharp without being ironed, if hung immediately after they come out of the dryer.  They are also fade resistant, shed water, lint, and stains and yet are comfortable as a standard button-down cotton shirt while providing a greater range of motion.
