There is definitely value to what @dembones22 and @hangulmalmotayo are saying about mitts and building wrist strength. That being said, I started using bag mitts w/o hand wraps and sprained my wrist pretty badly. I was punching a really uneven heavybag, and I was showing off a little bit because there was a bit of a crowd. Kept punching with the other hand, but I was in shock. Bag mitts are a cheap option, but I don't really recommend any mainstream pair of bag mitts.
