Duotone Grip 4 D/LAB 2025

Everyone strives to be different and loves to personalize their gear. But do you want to buy a surprise egg that custom boards often turn out to be? Or trust in a proven shape from a brand that has been at the forefront of board development for over 40 years?

Look no further, because here comes the GRIP D/LAB board range.

At DUOTONE, only true game-changing products qualify to carry the D/LAB logo. So what’s so special about these boards that makes them the first D/LAB products under DUOTONE Windsurfing?

Over the last 3 years, our board product manager, Dani Aeberli, and our QC specialist, Vasin Siritho, have worked on a new technology exclusive to DUOTONE. We call this FULL CUSTOM CNC.

We use a construction that is one hundred percent identical to that of the most high-end custom-made boards. Instead of using a mold to shape the EPS foam core, each EPS block is CNC-milled into its final shape. This ensures maximum precision and saves weight.

As with high-end custom board makers, the major advantage lies in the processing. We call this SINGLE PROCESS TECHNOLOGY, and it’s the key to our industry-leading weight-to-strength ratio.

Instead of combining work steps to save time and money, each step follows its own process. For example, instead of joining the PVC sandwich to the EPS core in a single step, we vacuum-bag the top and bottom PVC shields with the EPS core separately.

Also, instead of using standard 3 mm PVC elements across the entire board, we use thicker and thinner PVC plates depending on the stress areas, making the board lighter yet stronger.

For all D/LAB boards, we use our most sophisticated layup, consisting of more than 60 individual parts and components (nearly 20% more parts than our SLS Premium Sandwich Construction).

On top of that, we use the most high-end composite materials available today.

1. All the carbon fibers used are a mix of high-strength and high-modulus carbon grades, depending on the individual requirements of each board section. Our high-modulus carbon is also used in high-end products such as aircraft, Formula One cars, and our Platinum SLS masts, booms, and extensions.
2. Innegra is a high-modulus propylene with unbeatable tensile strength and ding resistance. It offers tensile strength comparable to Kevlar, but is significantly stiffer. In addition, Innegra is the best composite fiber for preventing dents.
3. We use our exclusive high-performance S_GLASS+ with an extra-high silica content, which offers much greater tensile strength and around 10-20% greater stiffness.
4. Finally, we use our exclusive DUOTONE SENTEX resin, impregnated with silicon nanospheres, which helps us reduce weight even further without sacrificing durability.

Instead of using a similar layup on all boards, we use a DISCIPLINE SPECIFIC FLEX CONSTRUCTION for all our D/LAB boards, because the demands of different disciplines (wave, freestyle, freeride, racing) and conditions vary considerably.

1. Racing boards are designed to deliver maximum performance (instant acceleration and V-max). That’s why they need to be as stiff as possible. To achieve this uncompromising stiffness, we use an exceptionally high carbon content in all FALCON D/LAB layups.
2. However, wave boards need a certain amount of “give” because they’re very short and can become too stiff and uncontrollable with a full carbon layup. That’s why GRIP D/LAB boards contain more Innegra and S_GLASS+. These high-tech composites have much greater tensile strength, helping prevent breakages after big landings. To still achieve outstanding “spring-back” characteristics, which make the board more reactive and have a tremendous effect on acceleration, we use unidirectional carbon reinforcements along the board.

Last but not least, every single board size has its own layup. That’s the final stage of individualization in construction.

The result speaks for itself: the D/LAB boards are approx. 500 grams lighter than our SLS boards and up to a full kilo lighter than other series-production boards. And for the first time, a production board can compete with even the lightest custom boards out there.

Yet all of this is achieved without any sacrifice in durability, since we always follow our core motto: LIGHT DONE RIGHT.

Please note that quantities will be strictly limited, at least in the first year - just like a real custom board. That’s why only the most popular GRIP 4 and GRIP 3 sizes will be available with D/LAB technology.

SHAPE DETAILS

Our GRIP D/LAB boards feature constantly evolving designs and constructions to ensure we remain at the forefront of development, backed by over 40 years of experience. We call them World Cup Wave boards because they’re engineered to satisfy the best of the best on all kinds of spots around the globe, from jumping-oriented side-on conditions like Pozo to down-the-line groundswell conditions like Hookipa.

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 accelerates slightly better thanks to 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 less-than-ideal waves.
