KS3 Lithium

The World's Lightest Production Wave Sail – Engineered for Championship Performance

The KS3 Lithium represents a quantum leap in wave sail design. We've taken one of the world's best-selling 3-batten sails and transformed it into the undisputed lightest production wave sail on the planet. Our 4.9m standard KS3 weighs 3.10kg – impressive on its own. The Lithium version slashes that weight by an astounding 30%, delivering just 2.1kg of pure, uncompromising performance. 

But the revolution goes beyond weight. Developed in partnership with Dimension/Polyant, Lithium's advanced materials create an entirely new riding experience. When underpowered, the sail feels tighter and more powerful, helping you plane earlier. When overpowered, it becomes softer and more forgiving than the standard KS3, delivering that coveted "surfy" feel that makes wave riding truly magical.

A Legacy of Championship Victories

Initially developed in 2013 by Kauli Seadi, Jeffrey Henderson, and Tom Hammerton, the KS3 has earned its reputation as the finest and most respected 3-batten wave sail in the world. Many consider it among the best wave sails, period, regardless of batten count.

The results speak for themselves: multiple Aloha Classic victories in the pro division, Bernd Roediger's 2022 PWA wave contest win in Capo Verde against the world's elite, and his 2024 Aloha Classic championship. The KS3 stands alone as the only 3-batten sail proven to dominate at the highest levels of competitive wave riding. For down-the-line wave sailing, many riders consider it simply the best in the world.

Explosive Response, Rock-Solid Stability

The KS3 is the most stable and direct sail in our lineup. Its 3-batten design dramatically reduces sail momentum, translating to lightning-fast response times and exceptional feel. The result? More explosive wave rides, quicker aerial maneuvers, and precise control exactly when you need it.

Even in flat water conditions, the KS3 excels. It maintains a locked-in feel across all wind ranges and seemingly refuses to become overpowered, giving you confidence in any conditions.
