The Session was built with stability and ease in mind. With more surface area than we've ever created, getting out of the water is a breeze and once you're up, you'll feel like you're floating with the level spine and grip rails reducing drag. Our All-Terrain construction makes crossing wakes and rougher water simple and smooth. Like all Radar Skis the Session is built with 100% carbon laminates. All-Terrain Core - Most forgiving construction. 100% Carbon Fiber - Consistent flex every time. Grip Rails 2.0 - Allowing your ski to engage with ease.
