ProGlide Men’s Razor Refills have five of our sharpest and thinnest (first 4 blades) anti-friction blades to get virtually every hair. The soft microfins on the blades help stretch and smooth your skin, while a microcomb helps guide your hair for a close shave. An even better Lubrastrip (vs. Fusion5) with more lubricants helps the blades easily glide across your skin.
