Thank you for viewing. This is a ZETT Prostatus SE series hardball catcher's mitt, the highest grade model. As it's the SE series, it's an even higher-end model than the standard Prostatus. I purchased it and broke it in, catching balls many times at a batting center. It has not been used on a field. I bought it, but I usually only play soft-ball recreational baseball, so I don't have a chance to use a hardball catcher's mitt, as it's stiff, so I'm putting it up for sale. Thank you. Material: Natural leather / (Face) J Steer Leather, (Palm) J Steer Leather ● Reverse hand opening ● Vertical type ● Made in Japan The opening is closed with a string instead of stitching, so it's easier to maintain than a regular mitt, and the patented structure reduces deterioration due to sweat, etc. Equipped with an SE series exclusive embroidered-style welder label. New J Steer Leather specification processed by Japanese tanners from North American raw hide, with a texture and luster reminiscent of domestic cowhide leather, and particular attention paid to the firmness and feel of the catching surface. Uses a thick, hard core to maintain the firmness of the catching surface and the best shape. The thumb curve gusset structure, unique finger cover type, and high-durability WEB support stable catching.
