I hit the bag with Windy Combat Sports Super Heavy Bag Gloves(14oz) for almost a year now. However, I don't spar with them. For sparring,I use my Century Training Gloves(16oz), because I was told the Windy gloves are not for sparring. My question is: Are they also suitable for the other things besides hitting the heavy bag or not? Are they good for hitting the focus mitts for example?
