The Exotics Tour Proto wedge features a 303 milled stainless steel face for the softest feel. At only 1.5mm thick, the face is backed by a hollow core filled with a newly-developed thermal plastic elastomer gel. The combination of the super-thin face and the gel produces an advanced level of feel and feedback not possible from traditional steel wedges.The Tour Proto's tour-grind sole minimizes turf interaction at the heel and toe, allowing for maximum shot-making versatility. Utilizing the latest shaft technology, the wedge features the new True Temper DG Spinner shaft. The Spinner incorporates a specially-engineered section just beneath the grip that can increase your ball's spin rate by as much as 700rpm.
