This Sanotan Heart of the Hide Catcher's Mitt features a conventional back and the One Piece Closed Web, which creates maximum strength and durability. With its 33" pattern, this glove forms a great pocket, which makes it easier to control the ball and scoop up pitches in the dirt. The Sanotan Heart of the Hide gloves are the perfect combination of weight and performance. Featuring a 15% average weight reduction, the Sanotan material comes from a Spanish tannery. The leather is titanium-based and chrome-free, making it hypoallergenic and non-irritating to the skin. The leather will keep your hand cooler and will dissipate perspiration faster than traditional leathers.
