TaylorMade SIM Max OS ...  The SIM Max OS version offers an oversized construction results in a larger sweet spot and more forgiveness across the entire face and also delivers the maximum distance.  The SIM Max is designed to deliver forged like feel in a distance iron.  The Max OS is 8% thinner for amazing ball speed and forgiveness!

• Speed Bridge™ - Revolutionary Speed Bridge technology strategically supports the topline of the iron to unlock explosive distance and forgiveness with improved sound and feel.
• ECHO® Damping System - Designed with energy channeling geometry to quickly eliminate harsh vibrations at impact delivering forged-like feel without sacrificing face flexibility.
• Speed Pocket™ - Patented TaylorMade technology engineered to maximize face flexibility for increased ball speed and forgiveness on low face strikes.
• Progressive Inverted Cone Technology - Engineers progressively positioned ICT towards the toe in both SIM Max and SIM Max OS to generate a draw bias in the longer irons and counteract the common right miss.
• Forgiving Shape Design - The head is shaped to deliver an unmatched combination of distance, forgiveness, and playability. Designed with a large face area to increase stability and wide sole geometry for forgiving turf interaction.
• Low Center of Gravity - A wide sole geometry, lightweight fluted hosel, 360° undercut and ultra-thin face shift mass from high in the clubhead down into the bottom of the sole for a low and back CG resulting in high, penetrating ball flights.  Additional stiffness in the head structure provides higher ball speeds due to reduced energy loss at impact.
