There are many kinds of gloves used when training. I can see the big boxing gloves fitting that description.
I train with fingerless 'bag' gloves. Some padding on the knuckles and palms, but otherwise open. They've saved some wear-n-tear on my knuckles when working on the bag, but still allow enough finger motion to allow for traps and catches.
i dont use wraps or gloves anymore when working the bag. My wrists took a bit of damage and i wish i would ahve bin a bit more delicate, but what can ya do? My wrists are pretty strong now(though i get those funny popping noises when i make circles with them )
yeah my JKD instructor had us all get 16 oz gloves, after you get used to them,. when you take them off you feal like you could just go all day. Also if you train with the added weight on your hands it has two advantages, one you will tend to hit harder because you are used to accelerating the extra weight, and two you will protect your knuckles a little better when hitting a bag, even with wraps and bag gloves you can still cause some dammage to your hands from long term use of a bag.. of course some people don't see any dammage..
