Hitting Jack-It Training System Fast Pitch/Softball Youth Trainer (9 oz) - Purple

Great product; fits easily in baseball and softball bats...great for using during batting practice...highly recommended...

Great for price, easy to use and take off in a jiffy. This is the second one we’ve owned, had to buy it to replace a lost one.

Works as expected.

adds the weight needed to get overload training in. This is an easy way to get reps in with extra weight with out over loading and risking bad mechanics!

Purchased this to help with an 8u softball team. The weight is perfect for that age. I liked that it was not too heavy at the end of the bat since it sits where the handle meets the barrel. All girls who tried it showed improved swings with better control of the bat.

The boys like it. Hope is have more different sized

Nice little weight. Quickened my daughters swing quite a bit.

They fit well on the bat and they don’t slide off.
