Because now all our 2025 Wave >< Freestyle boards are made in a FULL CUSTOM TECHNOLOGY. This makes the 2025 SLS boards again approx. 200g lighter yet much stronger than boards made in the usual semi custom construction: STRONG-LIGHT-SUPERIOR! For further details please see below under D/LAB vs. SLS vs. ORIGINAL.

But for us custom made stops at the shape of the board because custom shapes often turn out to be a surprise egg. 

Our GRIP SLS boards are constantly evolving designs and constructions to ensure we are continuously at the forefront of development yet with over 40 years of experience. We call them World Cup Wave boards as they are engineered to satisfy the best of the best on all kind of spots around the globe, from jumping-oriented side-on conditions like Pozo to down-the-line groundswell conditions like Hookipa.

During development, the major inputs came from 3-time PWA Wave World Champion Victor Fernandez and our next gen heroes Alexia and Carlos Kiefer and Tobias Bjornaa. We have selected these guys as they all have a very contest oriented riding style. Therefore instead of demanding super specialised and extreme shapes they always aim for:

  • Boards that are super balanced and easy to control in all kind of conditions without taking on a life of their own, to score maximum turns and jumps
  • Boards that are super versatile to sail and allow front- and back foot riding to get the most out of each wave even when the conditions are changing
  • Boards offering a maximum wind range to avoid being forced to switch boards during the heat

Well isn’t that exactly what we all expect from our wave board? And that’s why Victor, Alexia, Carlos and Tobias are our most important assets in the development process. In fact, all our GRIP SLS production boards are exact replicas of their best boards from the PWA tour.


Now the most important question you need to ask yourself is which fin configuration best suits your personal riding style:

  • The GRIP 4 with its Quad fin configuration gives you maximum drive and grip for committed rail to rail turns, even in XXL waves
  • The GRIP 3 has a slightly better acceleration due an efficient rocker with a lower-drag entry, which is especially helpful in jumping conditions. The Thruster fin configuration allows for earlier tail release for tighter/slashier turns, even in non ideal waves


At DUOTONE, the main objectives for all our products are weight saving but at no cost of durability and offering an unmatched plug & play setup. Cause these are the 2 things that help everyone, from beginner to pro level. 


Here is what we did to the 20.25 GRIP SLS lineup:

  • No 5 multi-setup fin-boxes: this just adds unnecessary weight and drag and is always a compromise since every fin configuration requires a different board shape (bottom and rail shape, outline, scoop-rocker line) to exploit its full potential. It also prevents the board from becoming tail-heavy/sticky. Plus finding a good working setup with 5 boxes is just the opposite of plug & play. 
  • The mini mast track reduces the weight in the critical nose area. It also reduces the risk to misplace your mast base while still providing just the right amount of length adjustment for all riding styles and sail sizes. 
  • The mini side fin boxes no longer offer any adjustment to prevent misplacing your fins. Now all adjustability for different riding styles and sail sizes is done through the center fin(s) only - simple and lightweight!
  • Our exclusive FULL CUSTOM layup based on over 40 years of experience got refined by DUOTONE chief board construction and QR manager Vasin Siritho.
  • Even the artwork got weight optimised by switching from heavy PVC to ultralight water-transfer stickers. 

All these efforts result in the best weight vs. durability out there. 

In addition, they simply work to their best right out of the box, just plug & shred.


YOUR NEW GRIP SLS DREAM MACHINES ARE READY AND WAITING FOR YOU TO TAKE YOUR RIDING TO THE NEXT LEVEL!

Great Product
Size: 90 Count (Pack of 1)
Life Extension’s Neuro-Mag Magnesium L-Threonate is a standout supplement designed to support cognitive health, and after trying it for several months, I can see why it’s so highly regarded. This product contains magnesium L-threonate, a unique form of magnesium that’s specifically formulated to cross the blood-brain barrier, making it highly effective for brain health. Each serving (three vegetarian capsules or one scoop of the tropical punch powder) delivers 2,000 mg of magnesium L-threonate, providing 144 mg of elemental magnesium. Here’s my take on its performance, benefits, and overall experience. Pros: • Cognitive Support: I noticed improved mental clarity and focus after about two weeks of consistent use. Tasks that require working memory, like recalling details or multitasking, felt smoother and less taxing. This aligns with research indicating magnesium L-threonate’s ability to enhance synaptic density and cognitive function, particularly in aging individuals. • Sleep Benefits: While not marketed primarily for sleep, I found that taking it about an hour before bed helped me fall asleep faster and wake up feeling refreshed. This echoes user experiences shared on platforms like X, where some reported better sleep quality and daytime alertness. • High Absorption: Unlike other magnesium forms like oxide or citrate, which are better for whole-body benefits, magnesium L-threonate is designed for brain absorption. Studies cited by Life Extension show it can boost magnesium levels in cerebrospinal fluid by 15% in animal models, which likely contributes to its cognitive effects. • Clean Formula: The capsules are gluten-free, non-GMO, and vegetarian, with no major allergens or unnecessary fillers. The powder version has a pleasant tropical punch flavor, making it easy to mix with water or juice. • Trusted Brand: Life Extension’s rigorous testing for purity and potency gives confidence in the product’s quality. Their transparency, including offering Certificates of Analysis, is reassuring. Cons: • Price Point: Neuro-Mag is pricier than standard magnesium supplements, which might be a drawback for budget-conscious buyers. However, the specialized form and targeted benefits justify the cost for those prioritizing brain health. • Time to Notice Effects: While some users report benefits in as little as six weeks, full effects may take up to 12 weeks, requiring patience. Final Verdict: Life Extension’s Neuro-Mag Magnesium L-Threonate is a high-quality supplement that delivers on its promise of supporting cognitive health. Its ability to enhance memory, focus, and even sleep quality makes it a worthwhile investment for those prioritizing brain function. Great benefits and clean formulation make it a top choice!

Highly recommend for sleep, mood, mental health
Size: 90 Count (Pack of 1)
I recently re-discovered this supplement, and I'm buying extras left and right and recommending to everyone I talk to. I've been working on increasing my HRV and supporting my nervous system, and the L-threonate is a rockstar for that. I was taking glycinate for a few months, and I found an old bottle of this one and added just 2 capsules, and the effect on my sleep was immediate. Way better than melatonin. My Fitbit is tracking much lower restlessness and more deep sleep, and I actually wake up feeling refreshed ?? and before my alarm, even! I'm noticing lower anxiety and an overall better mood, and it's only been 4 days. This bottle definitely holds its value, and the price is good, especially if I can get these benefits with just the 2 caps and not 3.

Big winner for helping BETTER SLEEP
Size: 90 Count (Pack of 1)
Life Extension is top of the line on most things they have. also pricier than most, but I buy three items for them regularly for many years. This Neuro-Mag with L-Threonate is excellent for boosting better sleep. This is a newer addition to their line. I also suggest trying their Mult-B complex and their B-12 elite (sublingual) On nearly all items, their quality control is near THE TOP of all suppliers. They also have supported vitamin and supplement research on my items over the last 40 years
