If you are looking for a heavy bag gloves that will allow you to put more power behind your punches you should take a look at the Combat Sports MMA Training Gloves. These are well padded and offer great wrist support. They have a lot of padding over the front knuckles to protect both you and your sparring partner. Compared to other MMA sparring gloves these are a bit bulkier but the extra padding over the front knuckles really works to absorb impact and shock when striking and sparing.
Another good option for MMA heavy bag training is the Revgear MS1 Gloves. These are a bit more expensive than the other options but they really do provide some of the best protection and performance available. The padding over the knuckles is thicker than most and they have a good amount of padding on the palms as well. This will help you grapple and grip your opponent as well as striking. The only downside to these gloves is that the palms have some extra edges that may get caught on people in crazy grappling exchanges.
The other thing to consider with MMA glove selection is the quality of the leather and stitching. This will affect the longevity of your gloves as the stitching can start to tear or develop holes over time causing them to become insufficient for safe use. If you can afford it, opt for top-grain leather made from goatskin or cowhide. This will resist wear and tear better than cheaper gloves and also allow your gloves to feel like a natural extension of your hand. Gants mma sac de frappe
