Original Duotone product information

The following manufacturer specifications describe the product range when new. Your purchase is for the individual used item shown in the photographs.

The Duotone SUPER_HERO SLS was developed as an evolution of the standard SUPER_HERO. With a radical weight reduction of 450 grams, it is a massive update, as it now has the same ultra-light weight as the SUPER_HERO D/LAB.

But that's not all, because all our wave sails follow the same 3 design principles that set them apart from all other sails out there:

1_ Wind range 

This is our top priority. It describes how much wind you can cover with a single sail size. Ultimately, this means how many sails you need in your quiver and how often you have to switch your sail due to changing wind conditions. 

The most important factor in increasing the wind range is to avoid the sail from stretching/blowing . Lab and on water tests confirm that the total stretch depends mainly on the film thickness. Okay, you can partially compensate ultra-thin film by increasing the thread/yarn density. But the space in-between the threads will always stretch. For this reason, we use a relatively “thick” film for the large center panel above the window. No one else does this, as using an ultra-thin center panel is the easiest way to save weight, but it comes at a price.

2_ Maximum durability and longevity

Maximum puncture resistance against rocks and reefs is particularly important when getting washed in the waves. Also you want to use your sail for more than just one season even in hot places.

Lab and on water tests confirm that puncture and UV resistance depend EXCLUSIVELY on the thickness of the film.

3_ Ultra-light sailing weight

Low weight is the only criterion that helps everyone to improve and sail longer, no matter if you are a pure beginner or a World Cup rider. However, you have to distinguish between the weight on the scale and the weight on the water in your hands. When a sail stretches/blows out, it starts to feel heavier in your hands. That's why we are only interested in the so-called sailing weight. Yes, our wave sails are among the lightest on the scale, but it's only on the water that they play in a league of their own.

SHAPE FOLLOWS CONSTRUCTION 

Instead of simply using the same 3D shape, luff curve and twist pattern for all sails in every construction, each sail is completely redesigned and reengineered from the ground up. This is the only way we can exploit the full potential of stretch-free CARBON XPly, for example. This makes all SLS and especially D/LAB sails real game changers. That's the reason why it took us over 2 years to develop the new SUPER_HERO SLS.

Using the SUPER_HERO SLS you instantly feel its incredible ultra-light feeling with lightning quick reaction. And best of all it stays that way even when a gust hit in. The SUPER_HERO SLS combines ultra-light sailing weight with maximum wind range to take your wave sailing to the next level!

Key Features

Intelligent Carbon XPly Construction SLS

• Carbon XPly in the high-load top and foot areas, plus batten pockets → ultra-low stretch + maximum power transmission

• More flexible regular XPly in the body prevents overpowering and keeps the sail controllable

Light Done Right Construction

Radical 450 g weight reduction — same level as SUPER_HERO D/LAB — but without using thin film on the main panel.

👉 Maintains unrivalled wind range and long-term durability.

XPLY PLUS

Exclusive laminate (100/150 micron) → lowest stretch + best UV and puncture resistance on the market.

Super-Light Bumper

The lightest mast protector available, with integrated downhaul trim indicator slot.

Tech Features

3D Top Cap

Three-dimensional transition of downhaul force eliminates top flutter and widens the wind range.

Carbon XPly

Reinforced with unidirectional carbon → zero stretch in load direction, controlled elasticity elsewhere. Makes SLS sails feel more direct and efficient.

Double D Buckle

Exclusive two-part metal buckle (inspired by climbing harnesses & F1 helmets) → prevents slippage and ensures accurate trim.

Duratech Foot

Sail-foot seams are enclosed in a plastic channel to prevent chafing against board nonslip coatings.

Epoxy Batten

Durable epoxy laminate battens resist extreme stress and breakage.

HTS 2.0 Harnessline Trim System

Printed indicators show the exact centre of harness lines → no trial and error, always correct placement.

Individual Boom Length Indication

Correct boom length printed at boom height on the luff sleeve → no guessing.

Mini Batten

Short stabilisers prevent leech flutter.

Monocoque Fusion Body

• No more stitched panels

• 150–200 g lighter

• No panel “play”

• Stronger fused construction = extended wind range

One Piece Sleeve

Seamless leading edge → 80 g lighter + improved elasticity (no hard spots).

Polyester Webbing Only
