The new Heater S-550 irons are designed to help golfers have better mis-hits. The deep undercut cavity design promotes stability at impact and forgiveness on off-center hits. New lower Center of Gravity make it easier to launch for a high, strong, penetrating flight. As CG moves lower on the ball, it promotes a higher ball launch. The 17º lofted #3 iron was purposely designed like a #2 iron for golfers who don't want to play with a 17º lofted hybrid due to longer club length. Women's clubs are built 1" shorter than mens. Built with Apollo standard stepped steel iron shafts and Rexton velvet rubber grips standard size. Please allow 3 business days for the club assembly. Clubs are built to order for you; No exchange, No return.
