Work against air resistance (similar to swinging a bat in a swimming pool). Build swing strength, increase hand/bat speed, develop stronger wrists. 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.
- Slip the fins over the barrel of the bat.
- One size fits all baseball and softball bats, little league, high school and college.
- Assembly instructions included.
