This would force you to use your shoulder rotation to power the bat and not your arms. Problem is you want your arms to extend naturally after contact and the trouble would be developing this to do just that. What do you think Jack?? <<<

Their bent elbows just lowered to their side to complete the follow-through.

This distance increases substantially with batters who straighten the elbow during rotation. We are using this fact in the design of the vest. A few more tests are required before determining the final design.
