Duotone Unit D/LAB 4.0m Wingfoil Wing 2026
A used 2026 Duotone Unit D/LAB 4.0m wing in like-new condition — Duotone's top-of-the-range wing with the Aluula D/TX frame, supplied with its Fusion boom and bag plus a bonus FBC leash that doesn't normally come with it.
This is the current-season 2026 Duotone Unit D/LAB in 4.0m — the pinnacle of Duotone's wing range, built no-holds-barred for freeride, wave and freestyle. It's barely been used (if at all) and is in as-new condition throughout, with no holes, tears, rips or nicks. The 4.0m is the go-to size for stronger winds, lighter riders and wave riding, and this one is ready to go with boom, bag and a spare leash included.
- Aluula D/TX frame with Trinity TX — one of the lightest, stiffest frame builds Duotone make, so the wing feels featherlight in your hands and turns every gust straight into drive and instant feedback.
- MOD 3S canopy — a premium freestyle/wave canopy tuned for draft stability and smooth power with strong top-end control, so it stays locked-in and easy to handle as the wind builds.
- Fusion carbon boom & slim leading edge — the ergonomic carbon boom gives natural hand movement and the reduced leading-edge diameter cuts drag, so handling is fast, efficient and direct.

Frequently asked questions
What condition is it in? Like new. It's been very lightly used — possibly only once or twice, if at all — and is in the condition you'd expect from as-new: clean and tidy with no holes, tears, rips or nicks.
What's included? You get the wing itself, its Fusion boom, the original Duotone wing bag, and a bonus FBC leash — the leash doesn't normally come with the wing, so that's an added extra.
What size rider or wind is the 4.0m for? A 4.0m is a smaller wing suited to stronger winds, lighter riders, and wave or freestyle riding where you want a compact, fast-handling wing.
What is the D/LAB? D/LAB is Duotone's no-compromise, top-tier construction — the Aluula D/TX frame makes it exceptionally light and stiff, which is why it's the benchmark performance wing in the range.
Why buy used? You get Duotone's 2026 flagship wing in as-new condition for less than new money, with the boom, bag and a spare leash thrown in.
