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 jumpsBoards 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 changingBoards offering a maximum wind range to avoid being forced to switch boards during the heatWell 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 wavesThe 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 wavesAt 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!Shipping Notes

Really comfortable upgrade from my old desk chair
Color: Beige
My old desk chair had been getting pretty uncomfortable, so I decided to replace it with this white one. After using it for a few days, I can definitely say it’s been a really nice upgrade for my workspace.
My old chair was starting to feel stiff and uncomfortable after sitting for a while. This one is a lot wider and softer, which I really appreciate. Sometimes I sit cross-legged when I’m working on my laptop, and this chair actually has enough space to do that comfortably.
The flip-up arms are also really practical. When I’m not using them, I just flip them up and push the chair under my desk. My workspace feels a lot less cramped now.
The wheels roll smoothly and the height adjustment was easy to set up. I also didn’t expect to use the side pockets much, but I’ve been keeping a notebook and my tablet there, which is actually pretty convenient.
I mainly bought the white color because I wanted something simple for my home office, and it looks really clean in the room.
After switching from my old chair, working at my desk has been a lot more comfortable. It’s been great for longer work sessions, and overall I’m really happy I decided to get this one.

Love the design, comfort and ease
Color: Grey, Color: Grey
Assembly was a breeze with the Amazon Basics Ergonomic Executive Office Desk Chair. The instructions were clear and easy to follow, and I had the chair put together quickly without any hassle. This simple setup made the whole experience even more satisfying from the start.
In terms of comfort, the chair truly delivers. It provides excellent lumbar support, I assume it will make long hours at my desk much more enjoyable. The adjustable height feature lets me customize my seating position, and the flip-up armrests allow me to slide the chair neatly under my desk without worrying about damage.
Overall, I couldn’t be happier with my purchase. The chair looks stunning in my office and perfectly complements the decor. It combines style, comfort, and practicality at a fantastic value, and I highly recommend it to anyone looking to upgrade their office chair. I love you so much that I ordered another one for my husband’s desk.

Very comfortable
Color: Grey
I’m not sure if I am just transitioning from a very uncomfortable office chair, but this one is extremely comfortable. Very good dynamic lumbar support that reminds you that it’s there. Only cons would be a low back (I am 6’5”) but I’m not laying my head back anyways. Also the seat length is a touch short for me but standard size really. Great bang for buck with an open box deal. Easy to assemble. TBD on durability.
