Duotone Cosmic and Cosmic SLS SUP Surfboards

Duotone is launching two new high-performance all-wave SUP boards: the Cosmic and the Cosmic SLS

With the new Cosmic and Cosmic SLS models for 2026, Duotone is expanding its SUP surfing lineup with two high-performance all-wave boards designed for a wide range of conditions. Both models are aimed at advanced to experienced stand-up paddlers and promise maximum versatility, high performance, and a modern shape design for waves of all sizes.

A board for just about any conditions

The new Cosmic is based on a modern all-wave design. The rounded nose provides stability when paddling and makes it easier to catch the wave. At the same time, the narrow moon tail gives the board precise and responsive handling.

Underneath the board is a well-engineered bottom shape design. A mono concave in the front section generates speed and ensures that the board remains responsive even in weaker sections of the wave. In the mid-section, the concave transitions into a double concave, which improves stability and control. Toward the tail, the hull opens into a V-shape, which supports quick changes of direction and a smooth surfing experience.

Cosmic SLS: The Premium Version for Maximum Performance

The Cosmic SLS is designed for ambitious SUP surfers who want to get the most out of their equipment. The board is manufactured using Duotones’ FULL CUSTOM SLS construction. Each EPS core is individually CNC-milled and laminated using a high-quality biaxial composite PVC sandwich construction.

The result is a board that is both exceptionally light and stiff, enabling direct power transfer and an extremely precise riding experience.

Four fin configurations on one board

A special highlight of the Cosmic SLS is the 4+1 fin box system. In addition to the classic thruster setup, riders can choose between quad, twin, or twin plus trailer configurations.

The classic Cosmic relies on proven versatility

The standard Cosmic features a classic 2+1 thruster setup and is built using Duotone’s CUSTOM CNC Composite Construction. This construction combines a precision-milled EPS core with a composite wood sandwich layup.

The result is a board with an excellent balance of weight, stability, and comfort, making it suitable for both everyday use and challenging surfing conditions.

Four sizes for riders of different weights

Both the Cosmic and the Cosmic SLS are available in four sizes:

• 8’0″ x 30″ – 109 liters
• 8’4″ x 31″ – 124 liters
• 8’8″ x 32″ – 140 liters
• 9’2″ x 33″ – 157 liters

While the Cosmic accommodates riders weighing up to 130 kilograms, the Cosmic SLS offers additional performance for experienced surfers thanks to its lighter, fully custom construction.

Conclusion

With the Cosmic and Cosmic SLS, Duotone is launching two modern SUP surfboards clearly designed for performance-oriented wave riders. The Cosmic stands out as a versatile all-rounder with a balanced thruster setup, while the Cosmic SLS offers maximum adaptability and high-end performance thanks to its full-custom construction and innovative 4+1 fin concept.

If you’re looking for a SUP surfboard that works in just about any conditions, you should definitely keep an eye out for the new Cosmic models for 2026.
