DETAILED DESCRIPTION
Versatility and positioning
The Unit SLS sits between the Unit D/LAB and the Original, offering a compromise between power and handling. On the water, you will feel a lively wing that is still easy to control, suited to varied disciplines such as freeride, freestyle and surf.
Stability and drift
The MOD3 S canopy delivers steady pull and an even power distribution. In practice, this means controlled drift and precise directional control, very useful in wave sessions or downwinds where you ride without holding the wing all the time.
Feel and control
The Leading Edge and center strut in undyed PentaTX, combined with an Aluula center section, increase the stiffness of the wing. On the water, this gives a lively, responsive feel with smooth transitions and good re-acceleration when you need it.
Comfort and handle options
The Fusion handles offer an ergonomic shape that makes adjustments easier and helps you hold the wing for longer. If you prefer even more direct control for technical maneuvers, the boom option with pistol handle is available.
Eco-conscious design
Duotone uses a bio-based bladder that cuts the carbon footprint by 29%, along with plastic parts made of at least 50% recycled materials. Undyed fabrics limit chemical treatments while keeping durability intact.
Who it is for and when to use it
We recommend the Unit SLS for intermediate to advanced riders who want an allround wing that can handle committed wave sessions, downwinds and freestyle. It suits a wide range of conditions thanks to its varied sizes.
