The RS100 irons utilise a two‑piece hollow body construction, internally filled with specialised foam to create a solid yet responsive strike sensation. This foam absorbs excess vibration while allowing the heat‑treated S450 face to flex more effectively, producing clear feedback and enhanced speed.
The irons also benefit from a 20% thinner S450 face, designed to increase face deflection and generate higher ball speeds. This leads to improved distance consistency and strong performance even when the strike isn’t perfectly centred.
