The new Epic Forged irons are developed from precision engineering, meticulous craftsmanship, premium materials and innovative technologies for complete performance. They deliver incredibly pure feel, with exceptional sound and turf interaction at impact from a Forged 1025 Carbon Steel body and our Urethane Microspheres. For the first time, our world-class R&D team has implemented the Suspended Tungsten Core into a forged iron. It suspends the custom tungsten weight using Urethane Microspheres, allowing Callaway to precisely position the Center of Gravity. To give players more ball speed and distance, we've engineered our renowned 360 Face Cup and we've designed a new Variable Face Thickness (VFT) pattern to promote consistent ball speed and spin rates, all in an ultra-premium performance package.
