A cool butt plug design, the Ryder has a very solid torpedo shape, but it isn't all that wide so you get a good feeling of fullness without being stretched too far. A nicely long, fairly narrow neck too, so it's less likely to slip out at an inopportune moment. It has a 3.75 inch insertable length, 1.25 inch in diameter at the widest point and a 0.75 inch neck.
