Breathability and comfort are the essence of the BLACKHAWK!® Purpose Shirt. The Tac Flow 2.0 fabric represents the next evolution in fabric technology. It's designed for maximum airflow, with small pinholes in the fabric to keep the wearer cool. The back features vertical vents with a mesh backing for further breathability. There are three main exterior pockets for storage, as well as a pen pocket. The textured fabric reduces printing, and the breakaway snap placket provides quick CCW access when needed.
