Callaway Men's XR Pro Hybrid In the XR Fairway Wood, we've started from scratch and changed everything from our Face Cup to the shape to make golfers even longer than they already are; It's led by a next generation Forged Hyper Speed Face Cup that's up to 36% thinner Higher MOI and Our Lowest CG Ever In A Hybrid We've completely redesigned the head shape to create even more forgiveness and the lowest CG we've ever had in a hybrid; That's what happens when you position more weight lower and around the perimeter More MOI and Ball Speed Our re-engineered Internal Standing Wave is the ultimate team player; It's a refined way to increase MOI and still give the face cup the freedom to flex for more ball speed More distance, lower spin and versatility are the highlights of adding a re-engineered Internal Standing Wave And the completely redesigned shape provides a shallower face for increased forgiveness from the fairway
