More mass is concentrated in the sole for a low center of gravity (CG) and higher launch. The firm's proprietary face insert has three thicknesses to spread the sweet spot (hot zone) over a wider area and improve output on mishits. Thanks to an extra-wide sole, the head sits flush with the ground, so proper face alignment is a snap. The DXi is available in 13° (3+), 15° or 18° lofts.
