Gillette ProGlide is a completely modern cartridge that features a state-of-the-art microcomb, plus expertly designed, durable, super-sharp PROBLADESTM and many other advantages. With post-blade lubrication, a spring-loaded base stand, a triple-blade stabilizer, and a precision trimmer blade on the back of the cartridge, you'll enjoy incredible closeness and comfort. Benefits: Micro-comb guard to guide hairs towards the blades. Behind the soft, flexible microfins of the ProGlide cartridge, a unique microcomb helps gently guide hair toward the blades. The microfins stretch the skin in front of the blades to create an even surface, while the microcomb positions the hairs for optimal cutting. Padded Lubrastrip for smooth gliding The ProGlide PROBLADESTM are enhanced with Gillette's iconic Lubrastrip cushioning. This thin, orange pre-lubricated strip activates when wet and slowly releases its ingredients onto the skin for a smooth glide. The Lubrastrip also fades with use from orange to white, indicating when it's time to change the blades. Our sharpest blades (*blades 1 to 4) for incredible closeness ProGlide PROBLADESTM are coated with an anti-friction layer, which helps ensure a comfortable shave. As there are 5 blades in one cartridge, each hair can be cut up to 5 times in a single pass, achieving an impressive close. ProGlide PROBLADESTM are our sharpest blades for maximum closeness and are extremely efficient and durable. Spring-loaded blades for a comfortable shave The ProGlide's carefully positioned blades are individually spring-mounted, allowing them to move up and down within the cartridge. In this way, the blades can automatically react to the uneven surface of the skin. Combined with the ProGlide shaver's FlexBall pivot and ergonomic handle, this technology ensures a comfortable shave even in difficult areas.
