CHICAGO—Polyurethane is at the heart of the latest generation of Wilson's Distance D300 irons.
The new golf clubs incorporate Power Holes, which are through-holes that surround the club's entire face. These allow the club's face to flex, and weight is moved to the heel and toe of the club to maximize forgiveness, Wilson said.
The holes are filled with TE031 polyurethane to improve the feel, and absorb vibrations to give a better sound, the company added.
"The D300 irons build and improve upon distance, forgiveness and feel of the C200 Irons," Michael Vrska, global innovation director at Wilson Golf, said in a news release. "The Power Holes have been refined specifically for the 'D' or 'Super Game Improvement' player to provide significant distance and accuracy improvements."
Both steel and graphite versions of the clubs are available, according to Wilson.
