Mizuno Rosin Bag

The Mizuno Rosin Bag is an essential piece of equipment for any pitcher who wants a consistent, reliable grip in every condition. Packed with quality rosin powder, a light tap of the bag draws just enough moisture off the fingertips to sharpen command — from a well-located fastball to a sharp breaking ball. Durable and simple to use, it's the same time-tested tool trusted at every level of the game, from youth travel ball to the professional ranks. Keep one on the mound, in the bullpen, and in every player's bag so grip is never a variable when the game is on the line.

Coach's tip: Have pitchers tap — not squeeze — the bag so they pick up a light, even coat of rosin without overdoing it. Care: Keep the rosin bag dry between outings and store it in a sealed pocket so the powder stays fresh and effective.
