Wondering if anyone else has seen this. Doing a Fed game today when the first batter came to the plate with a 1" band around the bicep area of her right arm ( right hand batter ). I asked her what it was and she said it was a sports band meant to reduce vibration from bat/ball contact. I thought for a moment about "jewelry" and it didn't seem to apply. I thought about the velcroe material used and didn't see it as a safety issue. I also thought if it actually did any good and realized it wasn't any of my business.

Has anyone seen this and does anyone see a problem with them? 6-7 players were using them.

no problem - but 6-7 girls probably wasted $10 ...
