With over 40 years of expertise, Duotone delivers a board that’s exceptionally light, durable, and responsive, ideal for the most demanding wave conditions around the world.
Advanced Custom Technology
The GRIP SLS 2025 is constructed using our FULL CUSTOM SLS TECHNOLOGY, resulting in a board that is 200g lighter than traditional models yet stronger and more resilient. This exclusive technology, crafted with precision, ensures unmatched durability and performance without added weight.
The mini mast track reduces weight in the nose area, while optimized fin boxes prevent unnecessary adjustments, offering a truly plug-and-play setup. Every board in the GRIP SLS line is crafted with input from champions like Victor Fernandez, ensuring a balance between versatility and performance.
Wave Performance and Versatility
The GRIP SLS is engineered for maximum versatility, enabling riders to excel in a wide range of wave conditions—from powerful down-the-line waves to onshore conditions. With two fin configurations (Quad and Thruster), you can tailor the board’s performance to suit your style. Choose the Quad setup for maximum drive and grip in big waves or the Thruster setup for enhanced acceleration and tighter turns.
Superior Control and Handling
Designed for smooth handling and precise control, the GRIP SLS features a balanced shape that provides an intuitive feel. This board excels in both front- and back-foot riding, making it easy to maintain speed and control across different wave sizes and wind conditions.
Lightweight and Durable Design
Constructed with ultra-light materials, the GRIP SLS includes a weight-optimized design, reducing unnecessary components like multi-fin boxes and heavy artwork. With its refined construction, this board offers an unbeatable weight-to-durability ratio, delivering high performance for every session.
