Had this bat for like 2 seasons very good dependable bat! Clearly it’s a good bat because it hasn’t broken and we haven’t had any issues with the size or weight of the bat! The grip is probably only a season old so could probably use new grip or maybe could be used for like one or two more seasons! It is scratched up on the end of the barrel and then there are just paint chips all over the barrel. It’s a usssa bat and can be used in all temperatures unlike composite bats this on if aluminum. 1 piece and has a barrel diameter of 2 3/4 inches
