PARAWING / WING FREEFLY / ASSIST / PRONE
SLS stands for Strong Light Superior and is your gear that empowers you to push your limits and strive for peak performance without compromise.


OVERVIEW
The Paradox SLS was born along our Stash 2026 parawing development. Broadening the range of use when riding with a parawing doesn’t just come from advancements in the latest wings, the board plays a crucial part in take-off efficiency. Since the goal is free flight, this shape is crafted with pumpability and good turning control in mind, making it the ultimate weapon to shred the bumps.
The pulled-in surfy outline, step tail and enhanced rail bevels reduce the bottom area for good displacement of the water, so the foil can be pumped with the board still being on the water’s surface. This results in highly increased take-off efficiency, allowing to get up on foil with less power in the wing. The low rocker and front foot make pumping between sections efficient and the reduced thickness with recessed stance area adds great control and a connected feel through turns.
The board is equipped with front footstrap inserts and built in our lightweight Biax Carbon construction to keep swing weight to a minimum.
The DUOTONE Paradox SLS is the ultimate toy to tackle the bumps with the parawing, but with its surfy approach it can be prone foiled, ridden with foil assist or simply used for winging with advanced level and freefly focus.
*Footstraps not included. V-Strap or Single Strap available separately.
PARADOX SLS vs. SKYBRID
Both boards are mid-length shapes, both work for a variety of disciplines like Wing Foiling, Parawing, Foil Assist and Prone Foiling (in small sizes). Here’s what sets the Paradox SLS apart from the Skybrid:
+ Lower rocker: Paradox SLS takes off earlier & pumps more efficient, which is important when downwinding – less controlled when going faster with the wing vs. Skybrid, which has the front foot higher.
+ Reduced bottom surface (more bevelled, pointy nose, step tail): Can be pumped out of the water through legs better vs. the wider bottom of the Skybrid, which offers more stability and ease of use in return.
+ More maneuverable/agile vs. Skybrid, making the Paradox SLS the more surfy option for the more advanced rider.
+ Longer esp. in bigger sizes. Adds glide for earlier take-off with Parawing. Smaller volumes are similar in lengths – for more advanced riders / windier conditions.
+ Lighter construction (more like Crush/Midfish), with front strap option only, to avoid jumping – Skybrid can be jumped and ridden with both feet in straps!
Parawingers and advanced Wing Foilers riding the wing flagged in small surf or river bumps – mainly strapless – will really like the Paradox SLS, especially with slightly higher level. Wing Foilers of all levels and those riders going faster will benefit from the stability and control at speed of the Skybrid, especially when using footstraps and doing the occasional jump.
PARADOX SLS vs. MIDFISH
The Midfish – our dedicated Foil Assist board – is also a good option for Parawinging – especially for windy conditions – and offers great control in turns. The Paradox SLS, on the other hand, gets up on foil quite a bit earlier compared to the wider Midfish, allowing to ride less powered up and be more efficient when parawinging. The Paradox SLS can also be used for Foil Assist downwind sessions for that same reason.
HIGHLIGHTS
Earliest Take-off
Highly efficient when pumping up onto foil, allowing for earliest flight when used with parawing.
Efficient Pumping
Low rocker and front foot allow for efficient pumping projection through sections while downwinding.
Low Swing Weight
Reduced nose and tail area and light construction make the Paradox SLS extra responsive.
Turning Control
Thin recessed deck with wide stance area adds control and connected feel with the foil.
Versatile
Ideal for parawinging, but also works great for winging, with a foil assist and even to get into prone, accommodating a wide range of riding styles and disciplines.
TECH FEATURES

OPTIMIZED OUTLINE
Slightly longer and narrower outline enhances glide and take-off, with surfy nose for reduced swing weight.

LOW ROCKER
Low rocker from tail to front foot allows for earliest possible take-off glide and makes pumping efficient and forward driven.

HIGH APEX RAILS
Increased rail bevels and high rail apex offer clearance in turns and reduce bottom area for clean water displacement and earliest release.

LIGHTWEIGHT CONSTRUCTION
Lightweight Vacuum Carbon construction offers durability and strength without adding unnecessary weight.

STEP TAIL
Step tail reduces area behind the foil for an early and seamless take-off.

THIN RECESSED DECK
Promotes direct connection to the foil and enhances stability.

WIDE STANCE AREA
Pulled all the way to the rail allowing for good offset, adding leverage over the foil and control through turns.

ADJUSTABILITY
Long foil tracks support a variety of foil preferences and styles.

FRONT STRAP INSERTS
Optional front foot strap inserts for riders seeking added connection to the board (straps not included, available accessory).
