Designed In Collaboration With Rickie Fowler
Becoming one of the best players in the world means demanding more from yourself and your equipment. The RF Proto irons are a product of 33 revisions over the span of a year to create an iron that exemplifies the look, precision and performance that a great player like Rickie desires. Cobra's R&D and Tour team worked closely with Rickie every step of the way, taking his direction on the overall design to create an iron unlike any other.

A True Work of Craftsmanship
Each RF Proto iron is carefully crafted using a two step process: forged and machined for 155 minutes using a computer-numeric-controlled (CNC) milling machine to ensure the most precise iron without any inconsistencies.

Signature Shaping
Careful consideration was taken to ensure every aspect of the shape ranging from the topline thickness, to each edge radius suited Rickie's eye. The design process began with Rickie hand shaping irons on a grinding wheel, and resulted in 33 different prototypes that were tested, and fine-tuned by Rickie himself. At first glance, one will notice the sharp edges and little to no offset that makes these irons strikingly different from anything played on Tour.

Tungsten Weighting
A high-density tungsten toe weight positions the CG right behind the hitting zone for the purest feeling shots with added stability on off-center hits.

Stock Shaft

KBS C-Taper Steel: Low launch, low spin, signature feel. The KBS Tour C-Taper Steel was inspired by Tour player feedback requiring a low piercing trajectory and superior shot control. Packed with signature KBS technology, the KBS C-TAPER shaft maximizes energy transfer, for a crisp feel, while optimizing shaft diameters in the taper and tip areas for low trajectory and spin control. Independent testing proves the C-TAPER shaft to average 5% more distance versus the market leader as well. On Tour, the KBS C-TAPER shaft is preferred by several of the world’s top players who favor shot control and crisp feel.
