Boxing, Kick Boxing and Muay Thai gloves are all similar and used for light to full contact training and competitions. They all have full hand coverage and although they are produced in different ounces, the sizes are identical. The hand compartment is the same size, but the amount of material between the hand and the striking surface determines the ounce. All of these gloves can be used for bag/mitt training, sparring and competition. Boxing and Kick Boxing gloves are the same in construction. Muay Thai gloves are usually made of harder foam and have extended cuffs to offer more protection to the wrists when clinching an opponent and trapping kicks.
