Cobra Golf UFi 4-GW Iron Set with Steel Shafts:

The Cobra UFi Irons feature a Metal Matrix face insert which is a nine-metal alloy that's 65% lighter than steel. This allows more weight to be shifted to the perimeter of the clubhead, providing high MOI (moment of inertia) for ultimate forgiveness along with a uniquely soft feel. The polymer topline design technology removes mass from the topline, promoting lower CG (center of gravity) for higher launch and improved feel. The wide-sole design with tungsten heel-toe weighting shifts weight distribution for high MOI and low-back CG for maximum forgiveness, high launch and superior distance.

The UFi irons (Ultimate Forgiveness irons) are by far Cobra's most technologically advanced irons to date. Designed by integrating multiple materials, these irons bring together an exclusive Metal Matrix face insert, polymer topline, tungsten heel-toe weighting and steel alloy body. Combined, these elements give you our highest MOI and lowest CG yet, for the ultimate in forgiveness.
