• A combination of VFT and Hyperbolic Face Technology creates a larger sweet spot and increases ball speeds across the face for longer, more consistent distance.
• Deep clubface/undercut cavity system enables engineers to precisely position the CG, increase face compliance and engineer the face of each individual iron to maximize ball speed.
• Feel Management Technology; Produced through a dual material medallion that fine-tunes sound and promotes a crisp, dynamic feel at higher ball speeds.
• Speed Step 85 Lightweight Steel Shaft; Steel shaft is available in both regular and stiff flexes along with lightweight graphite options.

X Hot: The New Standard in Distance ----------------------------------- Born from Callaway complete performance, X Hot Irons have created the new standard in distance for the irons category, allowing golfers to hit a 7-iron where they used to hit a 6. Renowned accuracy is just the beginning with an undercut cavity and Speed Frame Face Technology that make the face hotter, especially on the low CG, and new feel management technology that promotes crisp, dynamic feel at higher ball speeds. Without question, these are the longest irons in golf. Feel Management Technology Deep Undercut Cavity -------------------- Deep clubface/undercut cavity system enables engineers to precisely position the CG, increase face compliance and engineer the face of each individual iron to maximize ball speed. Speed Frame Face ---------------- The Speed Frame Face maximizes ball speeds all across the face for longer, more consistent distance. Technology borrowed from our drivers has actually been applied to these irons to produce the higher ball speeds and explosive distance that you’re looking for. Feel Management Technology -------------------------- This technology fine tunes sound while also providing crisp, dynamic feel and playability. Speed Step 85 Shaft ------------------- Steel shaft is available in both regular and stiff flexes along with lightweight graphite options.
