Sub 70 639 MB Plus Irons: Unlock the Confidence to Play a Blade

The Sub 70 639 MB Plus Iron is a product of our commitment to answering a recurring question from golfers worldwide: "Am I good enough to play a blade?" For those who have pondered this question and hesitated to invest in a club they may not feel skilled enough to wield consistently, the MB Plus is the solution you've been waiting for.

Precision Forged Craftsmanship: Just like its sibling, the 639 MB, the MB Plus is a classic-looking iron meticulously forged from a single billet of DT-4 super soft steel. This results in the same buttery feel and responsiveness that players cherish in a blade.

Enhanced Sweet Spot: The MB Plus has been thoughtfully crafted with a nominally widened top line, deepened offset, and a slightly longer heel-to-toe blade length. These adjustments have been carefully tested to ensure the largest possible sweet spot while still allowing for workability and delivering exceptional feel and feedback.

Confidence at Address: The larger blade size, deeper offset, and slightly wider top line collectively instill confidence at address, providing an answer to the question that once held you back.
