Rawlings' Sanotan Heart of the Hide gloves are the perfect combination of weight and performance. 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. This model is a Trap-Eze® Web, conventional back, 11.5" pattern.
