NIKE SW SUMO Squred 5900 Driver. New for 2008 Nike have updated their revolutionary Square driver. The SUMO² 5900 features a square-shaped head, a deeper face, a convex crown, and redefined body shape to increase ball speed and accuracy.
Why 5900 ? With the MOI (Moment of Inertia - a phrase much used by Golf Marketeers which basically boils down to high moi = straighter shots) at the maximum allowed of 5900, the SUMO² 5900 offers greater forgiveness on off-center hits with a tighter shot dispersion.
The result, claim Nike, is the straightest, longest and most accurate driver Nike Golf has ever made. Featuring Nike's Powerbow weighting, the weight in the SUMO² 5900 is repositioned to the farthest corners of the Nike PowerBow design, optimizing head stability and delivering ultimate accuracy.
The SUMO² 5900 has a multi-thickness face, which maximizes faster ball speeds from every point on the face.
