Z621 (Head Only)
$427.50
An iron-type utility club designed to match the Z521 irons.
The back face has a flat design that evokes a simple muscle-back look (similar to the Z521).
Furthermore, it inherits the high trajectory, optimal spin rate, and maneuverability characteristic of low-centre-of-gravity irons.
Furthermore, its unique bounce design provides a sense of security at address and also suppresses the head opening that often occurs on mishits.
The lineup consists of three models: U2, U3, and U4. They feature a soft iron body and an adjustable ignition angle.
