Introduce to the Mizuno's Inverted Cone Technology

The Mizuno JPX 800 XD Irons are the only irons with Burner speed, Burner power and Burner distance. Targeted at distance fanatics, Mizuno MP 53 Irons deliver up to eight more yards when compared to the average iron, thanks in part to their thin and flexible titanium faces.

Features:1. Thin, flexible and fast titanium clubfaces deliver higher COR (coefficient of restitution) for faster ball speed and therefore, longer distance
2. SuperFast technology provides more clubhead speed for more ball speed and more distance
3. Inverted Cone Technology is proven driver technology that expands the high COR zone for higher ball speed on mis-hits for more distance from shot to shot
4. Extra large clubhead and a deep cavity give the Mizuno MX-300 Irons an ultra-high MOI (moment of inertia), making them extremely forgiveable and easy-to-hit

The Mizuno MP-63 Irons combine SuperFast Technology and a flexible, thin fast titanium face that increases ball speed for more distance. Mizuno MP-68 Irons
's Inverted Cone Technology (ICT) promotes more ball speed and distance on off-center hits. It also features an oversized, stable head for forgiveness and ease of play.
