**Black November Sup Allround Duotone Flow 10’6 x 31 x 178 litri

Duotone Flow

Classic Shape. Modern Construction. The FLOW’s Malibu-longboard inspired outline isn’t retro for its own sake — it’s a precision tool.

The wider, rounded nose generates effortless early entry into waves and superior forward glide on flat water. The generous mid-section volume keeps the platform stable and predictable underfoot, while the tail’s refined outline allows smooth, drawn-out carves and pivot turns without requiring expert-level technique. The result is a board that genuinely rewards newcomers and intermediate paddlers while remaining satisfying and capable in the hands of more experienced riders pushing into steeper surf.

This is the board for fluid, unhurried riding — trimming down the line, walking toward the nose, leaning into a long carve, and simply enjoying being on the water.

CUSTOM CNC Construction

The FLOW is built with DUOTONE’s CUSTOM CNC composite construction — a composite-wood Sandwich layup with a lightweight CNC-precision-shaped EPS core and an unfinished look, developed and continuously refined from DUOTONE’s heritage in premium windsurfing and foil board manufacturing. The result is a great balance between low weight, efficient glide and great comfort.

A Shape That Grows With You

Whether you are taking your first steps into wave riding or refining a classic longboard style, the FLOW is designed to reward progression. The Malibu-longboard outline’s natural stability means newcomers can find their feet quickly, while the responsive rails and refined bottom contours give experienced paddlers the feedback they need to draw cleaner lines and surf more critically. This is not a one-season board — it is a long-term quiver staple.

Versatility Across Conditions

From dawn-patrol flatwater sessions to small-wave surf breaks and coastline explorations, the FLOW performs across the full spectrum of all-round SUP use. Its longboard-style shape handles chop and open water with composure, while the fin setup delivers precise tracking and maneuverability whether you are paddling straight or deep in a turn. This is the ideal board for European conditions: lake paddles, river touring, Atlantic beach breaks, and Mediterranean point breaks — the FLOW is at home everywhere.
