Gillette Fusion5 ProGlide Power men’s shaving razor with FlexBall technology, responds to contours and gets virtually every hair. It features 5 precision blades for incredible comfort (vs. Mach3). With Gillette’s thinnest and finest blades (first 4 blades, vs. Fusion5), ProGlide allows less tug & pull (vs. Fusion5). The Precision Trimmer on the back is great for hard-to-reach areas such as under the nose and sideburns. In razor sets, one razor blade refill equals up to one month of shaves. Fusion5 Proglide razors fit all Fusion5 blade refills.
