The 588 MB/CB combo iron set is precision forged from 1025 carbon steel. Every iron has an incredibly soft, yet solid feel. The MB irons feature a thin topline, minimal offset, and a compact design that allows for maximum workability and trajectory control. The CB irons feature a progressive cavity back, longer blade length, thicker topline, and more offset that the MB irons to inspire more confidence at address. Both irons feature tour zip grooves and laser milled club faces which maximizes the allowable groove dimensions while conforming to USGA groove requirements.
3-6 Irons are 588 Forged CB and 7-PW are 588 Forged MB
