These boxing gloves are great for punching, bag training, and sparring. They feature a two-layer foam padding and patented Thumb-Lok to protect your hands. There is a wrap around hook and loop strap for a snug fit, and the natural shape of the glove will not only conform to the shape of your hand but promote proper technique as well. These are 12 oz., but they also come in 8, 14 and 16 oz.
