Slow Pitch Softball Gloves: The Vinci 22 series is constructed of 5 ounce US steer hide leather. The 22 series utilizes our signature deep pocket design, which allows for better control and less spin. We have pre-treated the leather to reduce the break in time and get you on the field sooner. The 22 series utilizes strategically placed “shock pads” that are sewn into the lining for better palm protection by covering a larger area of the hand. The high-quality Deer Tanned Cowhide interior leather lined finger stalls are specially treated for a more comfortable feel. Our PC gloves are made the exact same way with just with more padding in the palm.
