I should mention, the amount of padding in a MMA glove over the knuckles is not much shy of the amount over the knuckles in a 12 oz boxing glove. The overall bigger size of the boxing glove makes up much of the weight. Padding over the knuckles is much closer between the two than you'd think.
Current MMA "training" gloves we use actually have more padding over the knuckles than 16 oz boxing gloves I use...but it's only over the knuckles, link below.
