The Cobra Optica SL-01 is a Tri-Material Construction from a forged aluminium 6061 body and milled face provides soft feel and true roll. An injected Urethane Body Cap further enhances feel and a forged stainless steel weight ring - for Low/Back CG and high MOI for greater accuracy and distance control.
