Description
Description
The Duotone eHarness Set is the waist-worn battery harness for the Duotone Foil Assist system. If you like the idea of electric assist but do not want extra weight sitting on the board or mast top plate, this is the part that makes the Duotone system feel so clean on the water.
Instead of putting battery weight onto the board, Duotone moves it onto your hips in a waterproof battery box attached to a purpose-built harness. In real terms, that helps keep the board feeling lively, balanced and much closer to normal foiling, especially when turning, pumping or trying to keep everything feeling natural beneath your feet.
Where This Sits In The Range
This is not a complete Foil Assist kit. The eHarness Set is the harness-and-battery-box part of the wider Duotone electric system, so it is the right choice if you need a replacement harness, want a spare, or you are building a setup around separate Foil Assist components.
If you want the full powered package, you should be looking at a complete Duotone Foil Assist set with mast, batteries, charger and remote. If you already have those other parts sorted and just need the body-worn harness element, this is the correct product.
Why Choose The Duotone eHarness Set?
- Keeps the board feeling cleaner – battery weight sits on your hips rather than on the board.
- More natural foil feel – less disruption to balance when carving, pumping and linking sections.
- Better freedom of movement – easier on the upper body than carrying batteries in a backpack.
- Built for real use – quick-release design, floating construction and practical water safety details.
- Reliable connection – the remote receiver sits in the battery box lid to help maintain a stable signal.

Is the Duotone eHarness Set a complete Foil Assist kit?
No. This is the harness and battery-box part of the Duotone Foil Assist system. It is ideal as a replacement, spare or building block, but it is not the full powered package on its own.
What is the advantage of wearing the batteries on a harness?
The main advantage is feel. By moving the battery weight onto your hips rather than the board, the setup stays more balanced and more natural under your feet, which is one of the standout features of the Duotone system.
Do batteries come with this set?
No. The working battery pair is a separate purchase. If you are completing a setup, you will need the Duotone Foil Assist Battery 7A Set (2pcs) 2026.
How do I choose the right size?
Choose S–M if your waist measures 71–89cm (28"–35"), and L–XXL if your waist measures 89–114cm (35"–45"). If you are between sizes and want help choosing, get in touch and we will talk you through it.
Who is this best suited to?
This is best suited to riders already committed to the Duotone Foil Assist platform who need the harness element specifically. If you are starting from scratch, a complete Foil Assist package will usually make more sense.
