2026 Duotone eHarness Set

Duotone eHarness Set 2026 — Foil Assist Battery Harness Ride longer, feel more, and stay in control. The Duotone eHarness Set is the smarter way to carry your Foil Assist batteries — keeping weight off your board and balanced right where it belongs: on your hips. Why the eHarness changes everything Traditional Foil Assist setups mount batteries on the mast top plate or board, adding unwanted weight and disrupting the natural feel of your foil. Backpack-style battery packs load your shoulders and throw off your balance in turns. The eHarness takes a different approach — both batteries (2 x 1 kg) are housed in a waterproof, buoyant waist harness. Hip-mounted weight doesn't fight your body through carves and transitions. You'll forget it's even there within minutes. Designed to stay out of your way The battery box connects to the mast top plate via a short cable leash, keeping your board and foil setup perfectly balanced. The remote control receiver is integrated directly into the lid of the battery box, positioned above the waterline for a consistent, interference-free signal — no more worrying about water disrupting your remote connection. Safety and fit are built in Getting in and out of the harness is effortless thanks to a magnetic buckle and Velcro neoprene strap. The adjustable design dials in a secure fit across a wide range of waist sizes. Need to ditch the harness underwater in a hurry? A single firm tug does the job. The harness is constructed from non-water-absorbing materials with built-in buoyancy, so it floats on its own and won't drag you under. A neoprene cover with a large zipper protects the battery box from opening under water pressure. Total system weight: ~3.76 kg (including box and batteries) Sizes: S–M: 71–89 cm waist (28"–35") L–XXL: 89–114 cm waist (35"–45")
