What boxing gloves should i use when doing bag work?

I have been boxing for a couple of months now and i am just wondering whether it is better to use actually sparring gloves (12oz, ect) for bag work or just use bag gloves?|||Professionals use 14-16 oz. bag gloves but you can really get away with using anything, really. Just make sure it's not Everlast.|||1 pair of hand wraps on each hand, and twins bag gloves, usually every brand has boxing gloves and bag gloves, boxing gloves are used for in the ring and if you use them on the bag you'll slide off and wont get better contact.|||depends on the weight of the bag and the texture.i use heavier gloves though|||12 oz..and 16 oz to spar..
