This MOLLE Window ID Pocket was designed to be used with the K9 Tactical MOLLE Vest and attaches to the vest in two ways. It can be used on the sides of the vest or on the vest top back. On the back of the Window ID Pocket are MOLLE straps and hook and loop. You can attach the Window ID Pocket on the top of the vest back with the hook and loop or use webbed MOLLE sticks to attach the Window ID Pocket to the vest sides. Webbed MOLLE sticks are sold separately. This Window ID Pocket is large enough to hold any of our patches and can hold two of the smaller patches. Inside the Window ID Pocket is a coordinating hook and loop strip so if you are purchasing the patches with hook and loop backs they will stay straight inside the vinyl pocket. The full side length of the window pocket opens for easy loading of your ID, paper work, or patches. The full top of the window pocket is clear heavy gauge vinyl and 1000 denier Cordura is used on the back of the window pocket.
