Question: Does this bag contain sand?
Document: Good size bag, the gloves and wraps are ok but you will need to upgrade the gloves if you really want to hit the bag hard, but overall a good package deal.
Great starter kit for the price! Have been wanting to get gear and equipment of my own for awhile, after shopping around this was the deal to go with even my boxing coach said I did good. Same set up he has in his spare room for when he has no time to get to the gym.
Good product for beginner.
Answer: no
