Intech's Thick Synthetic Leather Golf Iron Headcovers will protect your clubs from colliding against one another in the bag as well as offering protection from the weather elements. The 12-piece set are individually numbered from #3-9 and include 5 labeled wedge covers too. These slip on easily to modern game-improvement irons and have a magnetic closure to keep them secure onto the head while they are in the bag. The simulated leather look adds a touch of style while the padded foam-backed polyurethane (PU) supplies the protection.
