A hook fastener or hook and loop is the fastening system which uses two sides of material. The hook portion is the rough and scratchy like side and the loop is the softer fuzzier side. When placing the two sections together, the hook and the loop fabric attach to each other creating a bond, keeping the name tape in place during any activity. But not so strong that the name tape (or any other patch) cannot be removed as needed.   Army Specialist Rank OCP Patch Rank patches are essential to completing your uniform.
