Nike pushed the shape in all directions to improve performance. The SQ SUMO 2 5900 has a deeper face, a convex crown, and redefined body shaping to increase ball speed and accuracy.
Nike PowerBow Weighting: Weight is repositioned to the farthest corners of the Nike PowerBow design, optimizing head stability and delivering ultimate accuracy.
Multi Thickness Face: Nike delivered the geometry for stability, the shafts for control and speed, and now they’ve optimized the entire face to maximize faster ball speeds from every point on the face.

Review from the magazine
TG rating 
Nike claim the SQ SUMO2 5900 Driver is their straightest driver ever. A deeper face and even squarer design has further optimised head stability and produced the max MOI. Although lacking some distance and penetration for our pro, our amateurs found it extremely forgiving and easy to launch and that’s what this striking looking driver is designed to do.
Pro Verdict: This sounds and feels much better than the previous Nike square model but it didn’t suit me at all and everything wanted to go left.
Tester Comments: “A much improved version and I love the profile”... “Looks fantastic”... “My favourite square driver, feels quite powerful”... “Looks okay and is a solid performer”.
