Bought for my daughter who is in college and has some issues with overuse of her arm( she is a catcher) she goes to PT weekly. She has used it a few times so far and says its great her arm feels great after practice throwing upwards of 200 times a practice.

From baseball I would get tense tendonitis in my forearm through my bicep, using the K2 Adult Sleeve it has allowed me to throw again and enjoy baseball like I used to.
