They are "ok" at best. In general, they offer good knuckle protection but poor wrist and hand (bone) protection. If you are doing aerobic training, ie- not hitting the bag at full force and focusing on work rate, than they could be an option for you. I will stress this to you though- if you like to work hard and really dig into the bag, learn to wrap your hands with real handwraps. Once you get it down, it takes MAYBE 3 minutes to wrap both hands. The protection offered for the wrist and the small bones in the top of the hand is vastly superior, and is the main reason why handwraps were developed.
