One of the standout features of the Ping G400 irons is their innovative COR-Eye Technology. This technology combines a thin face with a unique internal cavity structure to create faster ball speeds and increased distance. The face flexes more at impact, resulting in a higher launch and improved overall performance. The COR-Eye Technology also helps to enhance forgiveness by increasing the moment of inertia (MOI), reducing the effects of mishits, and providing consistent distance and accuracy on off-center strikes.
