This is everything you loved about our Glide Rail sleeve but now in a totally see through silicone! The silicone Glide Rail Sleeve differs from the other VacuGlide sleeves in that it stimulates you with vertical ribs instead of horizontal ones. You’ll feel long continuous lines of pressure against your penis that have the advantage of additional rotation and sideways micro-movements. Grab the hose and slightly rotate your stroker sideways for a spiral stroking sensation that isn’t possible from horizontal or textureless sleeves!
