The 5.11 Tactical Shirt is loaded with 5.11 innovative features. The patented hidden document pockets are large enough to stash flight tickets, maps, etc., and subtle enough to stow-away a small backup. Triple stitched, and bartacked like the pants for excellent durability, these shirts feature pen pockets on the left sleeve, a back vent with Dri-X-treme mesh backing, hidden button-down reinforced collar and front pockets with a hook and loop closure. This shortsleeve shirt is made from 5.4 ounce 100% cotton canvas. Imported.
