This Wilson A2000 SuperSkin 13.5" Slow Pitch Softball Glove (WTA20RS20135SS) features a 13.50-inch pattern, a dual post web, and dual welting for a more durable pocket. On the back of each glove, Wilson has applied the man-made SuperSkin to help reduce excess weight, repel moisture, and shorten the break in period. Keep in mind that SuperSkin A2000 gloves are also known for being 2X stronger than an all-leather A2000.
