The Crimson and Gold 8oz Bag Mitt from Frank's Noble Art. All the greats wore Bag mitts, and we are on a mission to get boxers out of sparring gloves and back into Bag mitts for the punchbag bag. It's vital that you have the flexible thumb in training in order to make a proper first and punch with the knuckle part of the glove. These gloves are made from beautiful cow hide leather, diamond stitched wrist support band, and soft padding to make for a more comfortable punching experience.
