KEY INFORMATION
DUOTONE UNIT SLS 2027 - Wingfoil Wing in PentaTX and Aluula
What we like
- SLS Construction: 135g PentaTX frame and 82g Aluula Gold center panel
- Low-end power: the Unit's Leading Edge diameter is maintained on smaller sizes
- Direct response: revised canopy tension and tip twist mean the profile moves little under load
- Compact steering: the shortened center strut reduces rotational inertia
- MOD3s Canopy: the profile maintains its shape session after session
- Three colors: C04 Light Lime, C07 Off Green, and C03 Concept Blue Undyed, an undyed fabric
- Ten sizes: from 2 to 6.5 m², the three colors cover the entire range
Use
Freeride • Freestyle • Wave

Color
C04 Light Lime / C07 Off Green / C03 Concept Blue Undyed
Recommended inflation
7.0 to 11.0 PSI depending on the surface; never exceed the value indicated for the size.
The Fusion boom mounts on a wing that's already inflated to the recommended pressure. If the pressure is too low, the wing's structure won't be rigid enough. This means the boom won't properly seat or lock into place, and trying to force it will only damage your gear.

DETAILED DESCRIPTION
Balanced SLS construction
The SLS construction combines a PentaTX 135g frame and an Aluula Gold 82g center panel. This design balances weight and stiffness. It also balances price, and gives you a more direct response than classic structures. The center panel reinforces the most stressed area. It helps the profile remain stable under load. The wing transmits rider actions without a soft feel, while maintaining contained inertia. It suits regular riders who want a significant performance gain without upgrading to the full Aluula frame of the D/LAB.
Usable low-end power
Duotone has kept the original Unit's Leading Edge diameter on the smaller sizes. This gives the SLS drive from the first moments of pressure, where a thinner structure loses power. Early planing and pumping with a suitable foil directly benefit from this. The canopy tension and twist control then make the traction more consistent as the wind picks up. Acceleration remains progressive, and control is clear in gusts.
Profile Distribution and Tip Twist
The profile has been redistributed for 2027. It has less depth in the center and more towards the front quarter of the wingspan. This distribution improves power efficiency and, more importantly, stability in a neutral position when the wing is no longer loaded. Combined with optimized twist at the tips, this creates cleaner aerodynamics and a wing that doesn't deform when you depower. This is the most noticeable improvement when surfing and in swell.
Handling and visibility
The shorter center strut reduces rotational weight and brings the wing closer to the rider. Transitions, hand changes, and trajectory corrections require less amplitude. The new window placement improves downwind visibility without adding more openings in the canopy. The Fusion boom or Fusion handles can be mounted separately. The S boom is for 2 m², M up to 3 m², L from 3.5 m². The M handle is for up to 3 m² and L for larger sizes.
The C03 Concept Blue Undyed Colorway
Alongside C04 Light Lime and C07 Off Green, Duotone offers a third color, the C03 Concept Blue Undyed. This corresponds to the Unit SLS Concept Blue reference and features undyed fabric. It is available in all ten sizes, from 2 to 6.5 m², at the same price as the other two. The finish is duller than on dyed fabric, which is characteristic of unbleached fabric.
Freefly and surface area choice
The Unit SLS's balance allows it to remain stable when held by the Leading Edge handle. When surfing or downwinding, it follows the rider with minimal corrections and releases traction when desired. The 2 to 6.5 m² range covers a wide variety of conditions, with Duotone ranges from 27 to 45 knots in 2 m² to 7 to 18 knots in 6.5 m². The choice depends on your weight, skill level, and the body of water where you ride, as well as your foil. No chart can replace this, so call us.

FAQ - DUOTONE UNIT SLS 2027
For the regular rider who wants more lightness and response without upgrading to the full Aluula frame of the D/LAB. It is suitable for freeride and freestyle, and for wave, with power available from the first pump.
PentaTX 135 g frame, Aluula Gold 82 g center panel, MOD3s canopy, shortened center strut, and repositioned windows. Ten sizes from 2 to 6.5 m², three colors: C04 Light Lime, C07 Off Green, and C03 Concept Blue Undyed. Fusion Boom or Fusion handles sold separately.
The central Aluula panel reinforces the most stressed area. The profile moves little under load, and the wing transmits actions without a soft feel. The weight saving is noticeable in rotation and hand changes.
Duotone ranges go from 27 to 45 knots for the 2 m² up to 7 to 18 knots for the 6.5 m². A light rider on a large foil shifts these limits downwards. Give us your weight, your foil, and your usual conditions, and we will help you size it.
This is the third color in the 2027 range. Duotone references it as Unit SLS Concept Blue. Its canopy is undyed. It is available in all ten sizes, from 2 to 6.5 m², at the same price as the C04 Light Lime and the C07 Off Green.
Dry completely in the shade. Fold it once dry. Never store it wet. Respect the maximum pressure for the size, from 7.0 to 11.0 PSI. Aluula does not tolerate prolonged abrasion on sand and pebbles well. Place the wing on a towel between sessions.
Yes, this is a mounting requirement, not a comfort tip. The Fusion boom mounts on a wing already inflated to the recommended pressure for its size. If under-inflated, the wing does not offer a rigid enough structure. The boom will not position or lock correctly, and forcing it only stresses the equipment.
