The 3 blade technology offers a comfortable shave, along with the longevity that comes only with exchangeable cartridges. Comfort Guard includes 5 Microfins to bring you a close, comfortable shave, while the Indicator Lubrication Strip fades to white to show when you are no longer getting an optimal shave. Still a trusted choice, the MACH3 continues to give men around the world a great start to their day.
