These BAF defender shorts are made using real US Military fabrics. The AOR shorts are made using a 50/50 NYCO ripstop, and the OCP are a water repellant light softshell fabric (almost like an athletic short). All the pockets are mesh for ventaliation and for draining water. The fly has a velcro flap and hook, allowing to keep the pants thin and with no pressure points, and a zipper fly.
