The TaylorMade Golf SIM2 Max Driver features: What does Open Box mean? The item has never been used, however cannot be sold as brand new. Why? It’s no longer in retail packaging and / or is a customer return. Comes complete with manufacturer warranty. Forged Ring Construction unites a massive rear weight, a full carbon sole, crown and a milled back cup face. Creating a confidence-inspiring driver designed for increased stability and forgiveness. SIM Inertia Generator is designed to provide faster club head speed through advanced geometry and aerodynamics. A full lightweight carbon sole enables the redistribution of mass for a deeper CG and enhanced forgiveness. Speed Injected Twist Face improves ball speed by calibrating each head to the threshold of the legal speed limit with corrective face curvature also protecting against heel and toe mis-hits. TaylorMade's most flexible Speed Pocket design is engineered to maximize ball speeds and produce additional forgiveness on low face strikes. Headcover included - wrench purchased separately.
