Behind the Design: Unpacking the 2025 Evo SLS

Hi Manu, let’s talk about the new EVO SLS. Explain to us who this kite is designed for and where it sits in the Duotone range.

The EVO SLS is our all-around freeride kite. The SLS construction offers the best price-to-performance ratio in our range. It’s ideal for anyone who’s already kiting and wants to push their limits a little further—whether it’s for bigger jumps, getting into kite loops, or just looking for a higher-performance kite. The Evo SLS is the one to go for.

Tell us about the design for this season. What changes can we expect compared to last year, and what will riders feel?

Last year, the kite underwent a complete redesign, so we invested a lot of time in creating an entirely new model. This year, we focused on smaller refinements. I revisited every detail and tweaked various elements. For example, I refined the arc slightly, so this year’s EVO SLS is essentially a polished version of last year’s model.

The most noticeable change is the new six-point bridle system. Last year, some feedback suggested that when overpowered and fully sheeted out, the kite could lose some feel. With the new bridle, which is slightly longer, you get a longer bar stroke. This provides more control, even when the kite is fully sheeted out and depowered. The longer bar stroke also gives the kite a greater range.

Additionally, the bridle introduces a small, bright leg positioned far down the arc, almost horizontally. This helps control the horizontal movement of the arc, making the kite feel more compact, especially in gusty conditions. This results in a more solid overall feel.

The six-point bridle seems to be a major feature this year. Were there other small changes to the geometry and profile, and how do they impact performance?

Yes, we made several refinements. For instance, the trailing edge extensions were improved, and we adjusted the batten sizes for different kite sizes. These changes reduced tip flutter, so the kite is now more stable in the tip area, especially during loops.

We also made minor adjustments to the arc and sweep angle, which contribute to an overall more solid and refined feel for the kite.

Were there any material updates this year? How has the collaboration with Duotone’s lab influenced the SLS?

Yes, we upgraded the trailing edge material, using a slightly heavier fabric to reduce wear when the kite flutters on the beach. We incorporated Mod 3 material, which we borrowed from our wing division. It’s proven to be extremely durable over the past two years.

Have there been any changes to construction or manufacturing details?

One update this year is the batten pockets. Instead of being made entirely from cloth, the battens now sit in a small cloth pocket and are secured with a composite part. This keeps the battens in place better and reduces weight, making the kite lighter overall.

Let’s talk about settings and pressures. What are the recommended air pressures, and can riders tune the kite with different bar sizes depending on the speed they want?

For the Evo SLS, we recommend 7 psi as the optimal air pressure. This is where the kite performs best.

In terms of tuning, you have options like the back pigtail adjustments, which let you choose between heavier bar pressure with slower turning or lighter bar pressure with quicker turning. Bar length and line length also play a role.

I primarily developed the kite using the medium Click Bar with 22-meter lines, as it’s the most versatile setup. For larger sizes and lighter winds, you might want to use the big Trust Bar with 24-meter lines, which makes the kite turn faster. Conversely, for smaller setups or riders working on their first jumps or back rolls, a smaller Click Bar with 22-meter lines slows the kite down and offers more stability.

If you’re starting to learn kite loops, using a wider bar and longer lines can make the loop quicker and more dynamic. Ultimately, the kite works with every setup, so it comes down to personal preference.

To summarize, what makes this year’s Evo SLS stand out?

The Evo SLS remains our best all-around kite, delivering the best price-to-performance ratio with the SLS construction. The key updates this year include the six-point bridle, which offers a longer bar stroke and greater control, especially when sheeted out. Along with numerous refinements to the arc, sweep, and canopy tension, the kite is more solid, more controllable, and overall a better performer than last year.
