Using this Condor OC pouch is easy. First, open the hook-and-loop flaps. Then, place your MK3 or MK4 size spray inside the pouch. The adjustable flaps can be set to your preferred tightness. When you need to use the spray, just open the flaps quickly. As for maintenance, keep it dry and clean. Avoid exposing it to extreme temperatures. If there's dirt, gently wipe it with a damp cloth. And always check the hook-and-loop closure regularly to ensure it works well.
