2026 Duotone ePart eHarness

Duotone eHarness is the mounting platform for your Foil Assist battery box — a lightweight, buoyant harness that carries the batteries at your hips instead of on your board, so you keep the natural, unweighted feel of foiling while still getting the extra push when you need it. Buoyant construction means it won't drag you down if you come off, and it's quick to unclip and remove between sets. A dedicated cable channel routes neatly along your board leash, keeping the connection between the harness and your eMast tidy and out of the way while you ride. This listing is the harness only — the eHarness Battery Box is sold separately, so you can mix and match or replace either piece independently. Available in S/M and L/XXL to fit a range of body types.
