Baseball has a season. Training doesn't. Just because the calendar says opening day is off in the distance, that doesn't mean you get to sit around and wait for it. Your goals don't wait for cold fronts to pass by or rain to subdue. You need gear that keeps you in the cage no matter what the weatherman says.The Heater Fleece is a comfortable single sided fleece for easy layering with an open/loose fit bottom. Now available in team colors and for team purchase.
