I've searched the web a bit but all I get are online shops with very little help, so I'm hoping somebody here can answer my question.

I want to start using the heavy punch bag at the gym more this year but as the gloves there are old with holes and stuffing coming out of them, and smell very bad indeed I want to buy some of my own. My problem is that I'm not sure of what I need.

I assume wrist support is a smart idea, but 10oz, 16oz... is it the heavier gloves for the heavier punchbags, or is it for larger hands or for stronger people? Could somebody explain what I require please, and if you have some recommendations I'd appreciate it.

Many thanks!

EDIT: My background is martial arts and I use weightlifting gloves for striking the bag when practicing technique. I have been using the bag with boxing gloves for working on power and endurance (rapid powerful hits).
