If It Works Don't Fix It! That's right who in the world invented preventative care? Obviously someone looking to rip you off. Why change something that is already running. Wait till it dies on you before you bring out your tools to fix it.
Get this patch which is embroidered with white thread over black fabric and measures a perfect size of 4x1.25 inches. You can sew it on through the die cut borders or you could iron it on to your shirt. You can put this patch on to many places including your biker jacket or vest, wallet, belt, suitcase, hand bag. As long as you can sew it on it will do. Just listen to me and don't attempt to iron it on to leather. Ironing on works fine for other materials such as cotton shirts or jeans but will damage your leather if you tried.
