Duotone Unit SLS 5.5m 2025 Wing – Used Wing Foiling Wing
A used 2025 Duotone Unit SLS 5.5m — Duotone's best-selling all-round freeride wing in the premium SLS build — in good used condition. No tears, damage or repairs; just normal light signs of wear for an 18-month-old wing (see photos). One only at £499.
Please note: this is sold as the wing only — it does not include a boom or handles. These days almost everyone runs a boom rather than soft handles: it's more comfortable and gives you unlimited hand positions for pumping and riding. The Unit takes the Duotone Unit Fusion Boom & Handles, which you can add to your order if you need one.
The Unit is the wing that does everything. It's stable, forgiving and predictable in the hands, with easy handling, strong low-end power and neutral, drama-free drift through your turns and tacks — which is exactly why it suits everyone from riders finding their feet to advanced freeriders and wave sessions. If you want one wing to cover most conditions, this is the one.
This one is built in SLS (Strong Light Superior) construction — Duotone's premium layup that's lighter, stiffer and more responsive than the standard build, so it feels crisp and direct while staying durable. At 5.5m it's a versatile mid-size that covers a wide chunk of the wind range depending on your board, foil and weight.
