Power Fins
Some people say that batting donuts have been found to do more harm than good, as they upset your natural swing process and the weight distribution of the bat. Swing mechanics are not altered with Power Fins. Fins increase air resistance (similar to swinging a bat in a swimming pool).Power Fins help build swing strength, increase hand/bat speed, and develop stronger wrists.
Just slip the fins over the barrel of the bat. One size fits all baseball and softball bats, little league, high school, and college.


This is similar tot he running chute trainer but for hitting! It's awesome!
