Duotone Flow Bamboo

The Duotone Flow Bamboo —

Classic Shape meets modern construction. The FLOW BAMBOO features an outline inspired by Malibu longboards, but it isn’t retro for nostalgia’s sake — it’s engineered as a precision instrument. Its wider, rounded nose enables effortless, early entry into waves and delivers excellent forward glide on flat water. The generous volume through the mid‑section keeps the board stable and predictable underfoot, while the refined tail outline supports smooth, extended carves and pivot turns without demanding expert‑level skills.

The result is a board that truly rewards beginners and intermediate paddlers, yet remains engaging and capable for advanced riders pushing into steeper surf. This is the board for fluid, unhurried riding — trimming along the line, stepping toward the nose, leaning into long carves, and simply enjoying time on the water. FULL CUSTOM BAMBOO ConstructionThe FLOW BAMBOO is built using Duotone’s FULL CUSTOM BAMBOO construction — a composite-bamboo‑PVC sandwich combined with a lightweight, CNC‑precision‑shaped EPS core.

This build creates a board that is stiff, direct, and highly responsive: every paddle stroke and weight shift transfers instantly into the water with no delay or wasted energy. The result is efficient glide on flat water and confident, lively control when surfing. The bamboo sandwich technology also keeps the overall weight low while providing the durability needed for a board designed for frequent use in a wide range of conditions.

A shape that grows with youWhether you’re taking your first steps into wave riding or refining a traditional longboard style, the FLOW BAMBOO is designed to support and reward progression. The natural stability of its Malibu‑inspired longboard outline helps newcomers find balance quickly, while the responsive rails and carefully tuned bottom contours give experienced paddlers the feedback required to draw cleaner lines and surf with more precision.

This is not a board for a single season — it’s a long‑term essential in any quiver. Versatility across conditionsFrom early‑morning flatwater paddles to small‑wave surf sessions and coastal explorations, the FLOW BAMBOO performs across the full range of all‑around SUP use. Its longboard‑style shape handles chop and open water with confidence, while the fin configuration provides accurate tracking and agile maneuverability whether you’re paddling straight or carving deep into a turn.

It’s the ideal board for European conditions: lake cruising, river touring, Atlantic beach breaks, and Mediterranean point breaks — the FLOW BAMBOO feels at home everywhere.

Perfect for riders looking for a premium composite SUP board for wave riding, touring, cruising and high-performance paddleboarding.

Tech Features

FULL CUSTOM BAMBOO TECHNOLOGY: The FULL CUSTOM BAMBOO TECHNOLOGY is a full custom technology which is one hundred percent identical to high-end custom made boards. Instead of using a mould to bring the EPS foam core into its final shape each EPS block gets CNC milled. This ensures maximum precision and saves weight. Same as with high-end custom board makers the major advantage lays in the processing. We call this SINGLE PROCESS TECHNOLOGY and it is the key to our industry-leading weight-strength ratio. Instead of combining working steps to save time and money every single step follows its individual process. So for example instead of joining the PVC sandwich with the EPS core in a single shot we vacuum-bag the top and bottom PVC shields with the EPS core separately. For all BAMBOO boards we use our most sophisticated layup which consists of more than 20 individual parts and components. The bamboo sandwich on the top distributes peak loads evenly and further extends the overall durability again. Last but not least even every single board size has an individual layup. That’s the final stage of individualization in construction. Yet all of this is achieved without any sacrifice in durability since we always follow our core motto LIGHT DONE RIGHT.
Grab Handle: Ensures a secure grip and comfort when carrying your board. The handle features a double-sided design, so you can hold it from either side.
Duo Structure Pads: The 4 mm thick EVA pads offer the best balance between cushioning/comfort and grip/control. The center section features our signature diamond pattern, which ensures symmetrical grip in all directions. The heat-pressed process protects the EVA against abrasion, ensuring maximum durability. The rear section features a longitudinal cord-groove pattern that provides maximum lateral grip for your back foot, even during the most radical turns. We exclusively select EVA colors that don’t look dirty even after use and won’t fade even after hours in the sun.
DUAL LEASH PLUG: Stay connected to your board at all times thanks to the integrated leash plug. Our custom designed plug features two attachment points to ensure maximum reliability and safety, so you can securely attach your leash and stay firmly connected to your board.
Tail Design: SQUASH TAILThe squash tail is the most common tail shape among modern surf boards as it’s extremely versatile. It gives you more drive and grip during turns. Its rounded corners provide hold similar to a pin tail but with additional lift for improved maneuverability already at lower speeds and smaller waves.
2+1 Tri Box System: This system consists of 2 multi fin boxes (future fin compatible) + 1 US fin box. Two smaller side fins combined with the bigger center fin create a true Tri-fin setup that guarantees excellent maneuverability paired with additional grip and straight line paddle stability. The asymmetrical side fins also provide additional grip even during pivot turns.
Deck Shape: FLAT SPOT DECK SHAPEThe center of the deck is completely flat—right where you stand. Instead of standing on a round log, it feels more like standing on a jetty
this provides a stable base for better balance and maximum control.
Outline: The advanced wide point adds extra lift at the front of the board, making it easier to move around and allowing you to stay on the nose for longer. It also helps the board lock into turns by engaging a long section of rail from the tail all the way up to the wide point. The wider midsection provides greater stability for newcomers and/or in choppy conditions. The width also accentuates the outline curve, helping you to push harder into turns —almost like you would on a shortboard.
Rail Shape: SURFING STYLE RAILS> Harder, pulled down rails towards the tail for maximum grip during the top turns and more efficient glide.> Softer beveled rails towards the nose for smooth bottom turns and greater forgiveness when nose-riding.
Bottom Shape: Flat single-concave into V double-concave into opening V (front to back). >> In the front the flat single-concave improves the acceleration and take off on the wave.>> Just before the front foot it transitions into a V double-concave to ensure a stable riding position.>> Towards the tail the V is gradually increasing which results in a disconnected rocker (flatter rocker line in the center with increased rocker along the rail). The flatter center rocker results in improved planing power while the increased rail rocker improves the water release and turn-ability.
Rocker Line: LONGBOARD ROCKERClassic smooth longboard rocker adding smoothness and variety to your maneuvers. This encourages flowing turns rather than having to stall. The emphasis is on carving — not on old‑school nose lifting to force the board through a turn. The rocker naturally settles the board into its arc, so with only minimal input, the FLOW glides through each turn with ease.
EVA KICK-PAD: For better grip and foot positioning in pivot turns. Prevents foot from slipping outside of the pad area during swift turns.
