Nike SasQuatch Sumo2 5900 Square Driver With the new square geometry, the SQ Sumo2 5900 driver pushes the MOI, volume and impact efficiency to the USGA limits, all in one club, resulting in the straightest, most accurate driver NIKE has ever built. Oversized 460cc square clubhead geometry with Powerbow design moves weight to the farthest corners of the club for long, straight drives. One of the highest MOI's in golf for maximum stability at impact results in more accuracy even on mishits. Multi thickness face provides for a higher trampoline effect at impact across a larger cross section of the clubface. Deeper face, a convex crown, and redefined body shaping to increase ball speed and accuracy.
