This Pro Preferred 13" 1st Base baseball glove from Rawlings Gear features the Single Post Web, which gives it a stretchable web and forms a snug secure pocket which allows the ball to stick and not bounce. This glove also features a Double Ca-Thug style which allows you to mold the end of the glove to scoop the ball. The Pro Preferred line is made with supple Kip leather that provides a smooth look and feel. The Pittards performance sheepskin lining wicks away moisture and sweat to keep your hand dry and allows the glove to last several seasons.
