Srixon I-701 irons. The Srixon I-701 is a forged cavity back iron that is traditional in the playing position, but designed with a generous sweet area and a pocket cavity structure which allows for a lower and deeper centre of gravity. The result is an extremely stable clubhead through impact enabling low to mid handicap golfers to get the ball airborne easier for higher, straighter and longer irons shots. The Srixon I-701 irons combine a traditional profile iron with a progressive offset. The clubhead is a unique two-piece design with a forged 1025 carbon steel body and an extremely soft forged 1020 carbon steel face. The softer, thinner clubface allows for a very large, high coefficient of restitution (COR) area making the I-701 irons extremely long, even on off-centre hits.
