This is a High Quality, Low Profile, Baseball Style Cap with a 3.5" x 2" loop panel on the front for a Velcro patch. We include one of our patches, either Coyote Brown, OD Green, or Survival Resources Orange. The hat is Khaki so it is cool for warm weather and is made from poly/cotton. It has four vent holes, and a 3-3/4" x 1" loop panel on the back if you choose to add a name tag (not available at Survival Resources). It also has a 1-1/4" x 1" loop panel on top for an infrared marker (not available at Survival Resources). It has a quality adjustable back with plastic buckle. One size fits all.
