How many distance irons can say they have their own sound engineer? With an improved Speed Bridge and ECHO Damping System for better sound and forged-like feel, we went further than we thought possible to bring you a distance iron that feels better than anyone thought possible.
Explosive distance, enhanced feel and a sweet sound…What more could you ask for? A more refined Speed Bridge™ puts SIM Max•OS a step above its predecessor.
The ECHO® Damping System expands across the entire face from heel to toe, giving you forged-like feel in a distance iron.
We engineered Progressive Inverted Cone Technology to optimize accuracy with each iron in the set.
With an 8% thinner face than the previous class, SIM Max•OS gives you more ball speed and forgiveness.*
Increased speed claim based on SIM Max OS 7-iron vs. M6 7-iron at better player swing speed.
The Thru-Slot Speed Pocket™ completely disconnects the lower portion of the face from the sole of the iron and allows for a free-floating face. When combined with Speed Bridge™, the face maintains stability while delivering maximum ball speed.
