Manufacturer Says:

You can take advantage of short holes and knock approach shots close on longer tests with the Nike® SQ SUMO graphite irons (4-AW). The long blade length, wide sole and PowerBow Weighting deliver perimeter-weighted clubs and a high MOI (moment of inertia). The hot Cryo steel face provides a large responsive sweet spot, and the TPU insert dampens unwanted vibrations at impact.

Features

• Includes 4-9 irons, pitching wedge, and approach wedge
• High MOI (moment of inertia) provides greater forgiveness on off-center hits with a tighter shot dispersion
• SQ SUMO geometry for increased ball speed and accuracy
• Hot Cryo steel face provides large responsive sweet spot to amp up the distance
• TPU insert dampens unwanted vibrations at impact
• Long blade length and wide sole deliver an extreme perimeter-weighted club
• PowerBow Weighting has weight strategically positioned to move the CG (center of gravity) low and deep, increasing the MOI and creating a more stable iron at impact
