Radar Session Waterski | Prime + ARTP 2026

SESSION WATERSKI

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 fast and flowy with the level spine and grip rails working to reduce 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.

Our Open Water Series has three goals in mind: 1 - Quickly and easily plane to the surface. 2 - Very low drag. You can’t make it to the far end of the lake, or the length of the river if you run out of steam. 3 - It needs to still rip lake a slalom ski should. At Radar, we only design slalom skis that act like slalom skis. With the Open Water Series we took the mission to heart, adding more surface area than any other series in our line, cracking the traditional design code in the process. With the addition of Grip Rails and a flat spine, you have a ski that easily finds and maintains an edge despite its increased width. The barrier to entry into the slalom world just got lowered. Let it rip.

PRIME BOOT

The Prime was designed with simplicity in mind. A bungee lace on the upper allows for mobility while the static lace on the lower provides support. It offers great performance and comfort all while being super price conscious.

SHAPE

Flat Spot
Open Water skis sport an oversized flat spot which allow the skis to auto-level. Skiers of any ability level can hop on a Session and feel instantly at home due to its balance on the water. 

Straight Lines
The straight lines built into the Open Water series allow the ski to carve more continuously and let the ski roll on edge more naturally. This combined with our updated grip rails make for the most effortless and smooth lines you’ve ever dreamed of skiing. 

Grip Rails 2.0
The evolution of our grip rails was aimed to allow the ski to engage much easier. These angled rails also force water to the center of the ski increasing lift and decreasing drag. What you’ll feel is effortless flow and ease of turning. 

Level Spine
Open Water skis have a flat spine directly down the center of the ski. This allows water to flow cleanly down the center, reducing drag and making it possible to make endless turns without tiring out.
