If you don't use hand wraps your knuckles will get blisters or worse, also you will have much less support and will have sore wrists.-http://heavyfists.com/wp-content/uploads...
Yes! Especially if no one's there to tape your hands. After punching awhile, the gloves flatten. And because you are unable to bald a complete fist in your gloves the wrap helps them fit better. This leads to the ultimate protection. Plus, you need to get adjusted to the wrap. During a fight, your hands are wrapped tightly to help support your wrist.
Wraps are used in a cris crossed wrapping to help keep the medicarpal bones of the backhand from injury. Always good to use them.
If you wanna possibly hurt your wrist or fracture it go for it. That means yes you do.
Do you need to use wraps when using 12oz boxing gloves just for punch bag?
