The Nike Sasquatch Sumo Irons' PowerBow design and an ultralight Cryo Steel face combine to deliver an expanded COR (Coefficient Of Restitution) and high MOI (Moment Of Inertia). Now your entire game can experience the power of geometry.

• SQ Sumo Iron Geometry:
  Long blade length, wide sole and Nike PowerBow design deliver an extreme perimeter-weighted club and our highest MOI iron set yet
   
• Cryo Steel Face Insert:
  Lightweight Cryo Steel material in the long irons (#4 - #7) provides a large responsive sweet spot for maximum distance and increased forgiveness across the clubface
   
• Nike PowerBow Weighting:
  Weight is strategically positioned to move the CG (center of gravity) low and deep, increasing the MOI and creating a more stable iron at impact
   
• TPU Insert:
  A soft vibration dampening TPU material dampens unwanted vibrations at impact
   
• Shafts:
  Speed Step SL Steel - Unique high-strength steel alloy make this steel shaft 30% lighter than traditional steel shafts for increased club head speed and distance.
  iDiamana Graphite by Mitsubishi - Lightweight shaft designed specifically for the SUMO irons. This shaft promotes an increase in club head speed and high ball flight.
