The Stereo refined Bataleon's 3D shaping story. Their engineers developed the latest 3BT™ base contour in tandem with a new tri-radial side-cut and paired it with SideKick™ technology. The result is smoother edge-to-edge transitions, quicker response, and fewer hangups - playful when you want it, powerful when you need it. If Ethan and Halldór are down, we all are.
