By positioning mass at the edges of the clubhead, the perimeter weighting generates exceptional stability. At the same time, the undercut allows for a faster, more flexible face, delivering extraordinary speed, forgiveness, and launch across the hitting surface.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe super game-improvement category is full of speed, launch, and forgiveness-focused offerings. Yet, unlike most of its competition, the Max OS mimics the soft, rewarding impact sensation typically reserved for forged irons, thanks to Callaway's proprietary Urethane Microspheres. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe final element in Callaway's Max OS formula is its re-engineered Tri-Sole design.
