The Nike SQ Sumo irons feature the Nike PowerBow design and an ultra-light Cryo-Steel face that combine to increase the club''s COR and give it a higher Moment of Inertia for more forgiveness, even on off-center hits. They have a long blade and wider sole that provide extreme perimeter weighting, and a TPU Insert in the cavity that dampens vibration at impact for a softer, solid feel.
