The A2K® 12" first base glove uses the only the top 5% of Wilson®'s proprietary Pro Stock™ leather, ensuring that every aspect of this product is absolutely flawless. Craftsmen spend three times as long pounding, shaping and stretching the glove by hand than they do with any other glove from the brand. Its softness comes from natural fiber stretching, not from chemicals, surface treatments or substandard materials.
