Grip 4 SLS 2025

Design & Technology

SLS Construction – Strength Meets Lightweight Performance

The Duotone Grip 4 SLS 2025 Board features SLS (Strong Light Superior) technology, a construction method that redefines strength-to-weight ratio in modern kitesurfing boards. By combining precision-engineered layers of high-quality wood and reinforced composites, this construction delivers a board that is simultaneously rigid for explosive performance yet forgiving enough for smooth landings. Riders immediately notice the difference in energy transfer: every pop, carve, or jump feels more dynamic while maintaining stability in choppy conditions.

The SLS process involves meticulous layering and strategic reinforcement at critical stress points. As a result, the board can endure intense freestyle maneuvers without sacrificing responsiveness. In addition, the lightweight profile reduces fatigue over prolonged sessions, allowing riders to stay on the water longer while maximizing control. Whether performing technical tricks or cruising across varying wind conditions, the SLS construction ensures each movement is translated efficiently, providing unmatched confidence and precision.

Key SLS benefits include:

• Enhanced Durability: Reinforced areas absorb impact and prevent deformation.
