Tester profile
Tester: Romain Simonnot | Test type: Detailed innovation presentation and field feedback.
MOD3 fabric is stiffer and stronger.
The new MOD3 fabric sets Duotone wings apart. This material is incredibly stiff and much stronger than classic ripstop. When you're pumping, you'll notice significantly less wing deformation. This translates to more power and an incredible feeling of stability. Everything feels smoother, whether you're on flat water or riding waves.
The freefly handle provides optimal control.
Duotone integrated a rigid freefly handle at the front of the wing. It makes controlling and stabilizing the wing in a neutral position easier. You can keep it airborne effortlessly. This handle lets you maintain wing stability in freefly, especially during transitions or when the wing isn't actively propelling you. It's an essential feature for anyone who loves to Surf waves.
Handles or boom: the choice is yours.
The Unit D/LAB V5 wing offers two options: classic rigid handles or a boom. The rigid handles are easy to grip and deliver excellent responsiveness. Their new ergonomic pistol grip prevents chafing and hand fatigue. The boom, on the other hand, provides precise, continuous control, which is ideal for moving your hand along the entire length of the wing.
Aluula material: unmatched lightness.
Aluula is ultra-light yet extremely stiff, enhancing the wing's overall performance. Its lightness means you'll feel a real boost in power and stability, especially in lighter wind conditions. Aluula delivers both durability and long-term performance.
Romain's conclusion.
If you're searching for the ultimate wingfoil experience, Romain highly recommends trying this wing. It's already available at partner stores. Don't hesitate to get out on the water and test it!
Test by Hadou Brunner (video).
Tester profile
Tester: Hadou Brunner | Test type: D/LAB (Aluula) vs Classic (Dacron) comparison | Conditions: Freeride, jumps, light wind, and extreme conditions.
The different versions.
The D/LAB version features a stronger Aluula construction. This makes it lighter and stiffer. This positions it as a high-end wing. The classic version is built with Dacron. This makes it more accessible but also heavier. Finally, the SLS version offers a middle ground, with some improvements derived from the D/LAB.
Sizes and packaging.
The Unit V5 is available from 2.0 to 7.0 m². The D/LAB proves more efficient in smaller sizes due to the stiffness of Aluula. The classic is more versatile and especially forgiving on larger surfaces. The travel bag is compact and well-designed. The leash is not included and must be purchased separately. The wing offers customization options with rigid handles or a boom sold separately.
Handles and boom.
The boom offers better control for tricks and precision, which is ideal for a more natural grip. Rigid handles are lighter and provide good transmission with a different feel compared to the boom.
Inflation and Stiffness
The One Pump technology ensures quick and efficient inflation. Hadou recommends a higher pressure for the D/LAB to best utilize the Aluula construction. For the classic version, reduce the pressure for more comfort and flexibility.
Performance in Extreme Conditions
Hadou observed the D/LAB offers better handling in gusts with excellent stability. The classic is more flexible and forgiving, but it demands more effort to keep it stable. Both versions remain maneuverable and enjoyable.
Light Wind Performance
The D/LAB performs even better in calm conditions thanks to its lightness. The classic requires a bit more technique to harness its power in these conditions.
Versatile Use
The D/LAB is ideal for freerace and speed. It offers a more direct response. The classic is more forgiving and versatile, made for riders who prioritize comfort and ease. Both wings have improved stability in tacks and jibes due to optimized balance.
D/LAB vs. Classic: The Comparison
| Criterion | D/LAB (Aluula) | Classic (Dacron) |
