The comeback of the DUKE as a 5-batten Jump N’ Ride sail 2 years ago was a major success. It instantly became the most used and popular sail in the ION CLUB and DUOTONE PRO CENTERS worldwide.

Now with the DUKE SLS we take this concept to the extreme! But instead of just swapping the materials, we have developed this sail from scratch to utilize the full potential of the materials and to give this sail an additional character. Because depending on the board, the DUKE SLS behaves like a chameleon:

  • On lower drag single-fin boards (e.g. Freewave or small Freeride boards) the DUKE SLS has a slight forward pull (similar to the Original DUKE). 
  • On higher drag multi-fin wave boards, however, the pull is evenly distributed over both hands. On such boards, the new DUKE SLS has a very similar feel to the SUPER_HERO D/LAB making it really suitable even for proper wave sailing conditions.

But how was this made possible?

Well, it is a combination of an extremely sophisticated sail concept (3d-shaping, twist pattern and profile distribution) and the use of CARBON XPLY batten pockets. The DUKE SLS features a slightly forward draft position, but with a defined flexibility. We call this DEFINED DRAFT MOTION CONCEPT. Normally, this is a no-go for sails with “soft” epoxy battens, as any draft movement reduces the wind range. But this is where the CARBON XPLY batten pockets come into play: as Carbon has virtually no stretch, it locks the battens thus draft in its defined position - actually pretty similar to a Carbon batten.

Believe it or not, in this way we virtually merged the advantages of the Original DUKE with those of the SUPER HERO D/LAB creating the ultimate 5-batten Wave><Freewave sail.

Ok, so the DUKE SLS feels similar to the SUPER_HERO D/LAB - but what about the low end power? 5-batten wave sails offer great control, but usually suffer in the low-end as more battens make it harder for the wind to inflate the sail. That’s why we have incorporated the BATTEN FREE CENTER concept that we already use on the SUPER_HERO and the Original DUKE. Instead of the usual even batten distribution, the DUKE SLS features a bigger gap between the foot batten and the batten above the boom. This makes the boom area easier to inflate, resulting in a similar low-end power to a 4-batten sail. 

But it’s getting even better: due to the additional use of CARBON XPLY in the high load top and tack areas plus a STRIPPED TO THE MAX panel layout we were able to bring down the weight by a whopping 400-500g compared to the Original DUKE.

So what keeps you waiting - DUKE SLS the first sail morphing the advantages of a Freewave sail with a truly capable down the line wave sail.

Easy and simple: Exact Step-by-Step Guide to Reloading Your Balance
Reload type: One Time Reload
I found reloading my Amazon gift card balance much easier than expected. The process was simple and took about 5 minutes at most. Here are the exact steps to do it: ​Login: In the Amazon app or on Amazon.com, log in to your account. ​ Menu: Tap the 3 lines on the bottom right corner of your screen (next to Rufus, Amazon's AI). ​ Find Category: In the section highlighted "Shop by category," tap on Gifting & Registry (3rd option down in that section) and a drop-down menu will appear. ​ Select Gift Cards: On the drop-down menu, tap Gift Cards (first option). ​ Choose Your Action: "The Gift Card Shop" will appear. There you will have three options: "Redeem a gift card," "View your balance," and "Reload." ​ Start Reload: To add funds, tap Reload. ​ Select Type: Scroll down to "Add funds directly to your Amazon Gift Card balance" and tap which reload type you want (one-time, low balance auto-reload, or scheduled auto-reload). ​ Enter Amount: Choose your reload amount. The default is $25, but you can type in your own amount as well (the minimum amount is $5.00). ​ Finish: Tap the orange "Buy Now" tab. ***I used the Amazon app using the u i OneUI version 8.0 these Amazon app on Android version 16 (Baklava) on a Samsung Galaxy S25 Ultra. Others may have a slight variation of the menu setup on the Amazon app.***

Easy way to add balance
Reload type: One Time Reload
Reloading my Amazon gift card balance has been easy and convenient. I like using it when I want to keep a little money set aside for Amazon orders or make checkout quicker without thinking about which card I want to use. The process is straightforward, the balance shows up fast, and it has been reliable every time I have used it. It is also helpful for budgeting because I can add a set amount and then use that balance for regular purchases. Nothing complicated about it, which is exactly why I like it.

Monthly reload for Subscribe & Save Orders
Reload type: One Time Reload
Not a glamorous review, but a genuinely useful tip for Subscribe & Save users. I reload about $100 to my gift card balance once a month, a week or two before my S&S order processes. Amazon pulls each Subscribe & Save item as a separate transaction, which means 10+ individual charges hitting your bank account on before or on ship day. A headache for budgeting and a minor anxiety trigger if you're watching your account for unauthorized activity. Loading the balance first consolidates everything into one clean transaction. Your S&S order then pulls from the gift card balance rather than your card directly, and your bank statement stays tidy. The side benefit is built-in budget discipline. I set about $100 as my monthly Amazon ceiling - if my cart runs over, something gets pushed to next month. It's a simple system that keeps spending intentional without any extra effort. If you're a regular S&S user who wants cleaner finances and less ""wait, who charged this and what was that charge?"" moments, this is worth making a habit.
