TaylorMade 2020 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 most distance of any iron in the 2020 lineup.  The SIM Max is designed to deliver forged like feel in a distance iron.  In comparison of the key specs, the SIM Max OS model has slightly stronger lofts and more offset in the longer irons.   And, both models are quite a bit thinner than previous classes; the Max OS 8% thinner and the Max irons are an amazing 17% for amazing ball speed and forgiveness!

TaylorMade SIM Max and Max OS Irons ...  Common Technologies in both Iron Offerings.
• 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.
