UPE ARAMID Technology

The UPE Aramid wings features the most advanced technology on the leading edge and the strut.

The UPE Aramid, a true gem of textile technology developed by experts in nautical textiles.

How does it work?

  • The PET film ensures the connection between the elements and waterproofing.
  • The Aramid fibers are arranged at a chosen angle to block the fabric’s extension under load without unnecessarily adding weight to the structure.
  • The thin layer of UPE, lighter than on UPE 200, ensures strength. This tight weave of Dyneema fibers is a veritable shield.

These three laminated layers create a fabric that is both extremely lightweight, highly rigid, and very resistant to tearing.

Our exclusive assembly, tested in the laboratory and by the Pro Team, ensures unparalleled longevity for UPE Aramid.

The whole system is so rigid that 8 PSI gives you the rigidity of a UPE 200 at 15 PSI. It’s truly deformation-resistant.

Less pressure = less stress in the wing = less time spent pumping.

More durability, performance, and lightness: the holy grail.

UPE Aramid

The UPE Aramid is the lightest and stiffest material on the market. The sensations in hand are simply astonishing. The wing is both one of the stiffest and one of the lightest on the market, providing an entirely new sailing experience, all at an amazing price. It’s simply incredible and perfectly in line with our commitment to offering the best to as many people as possible.

At 85g/m2 (2 times less than Dacron!), this UPE Aramid present on the leading edge and the central batten ensures, in addition to a considerable weight savings (400g on a 5m2), an unparalleled gain in stiffness and reactivity. It’s simple: the wing no longer bends! We control its twisting through the Aramid axis and the design of the shape. Thus, deformations are no longer present.

In addition to its exceptional mechanical properties, this material also has a very low absorption rate. The wing gains very little weight when wet.

Obviously, a superb material without perfect assembly is worthless, and we have worked in infinite detail to ensure the reliability of the technical solutions for its implementation. For this, we have tested all known assemblies on traction machines and innovated with new and exclusive assembly methods at GONG to surpass the standards. Our wings have never been so robust.

Better than gold !!!

GFS V2 System Boom

The geometries of the handle support and elbows of the GFS V2 system introduced in 2025 bring notable improvements:

  • Less play, with a firmer, more direct contact for better control of your wing
  • 150 grams lighter for a set of handles and 40 grams saved on a boom
  • Zero rotation of assembled parts for zero wear
  • Assembly remains just as simple and easy with your Torx 30 foil key

A solution perfectly compatible with your textile handles, rigid handles, or boom in the GFS V1 system. You simply need to mount them on the V2 handle support of your new wing: learn more about the backward compatibility of the GFS V1 and V2 systems.

The boom with prepreg carbon applied in 4 directions enjoys the most high-end construction on the market to allow optimal rigidity with very low weight. Its oval shape offers an ideal grip which prevents fatigue, reduces the overall diameter of the boom, and increases rigidity. It is also covered with embossed EVA for perfect grip and comfort.

The fixing parts of the boom are designed to cancel out any play and to be completely removable, therefore scalable but above all extremely durable. We made the choice not to use sewn soft plastic whose lifespan is quite poor in the marine environment, under heavy loads and because of UV exposure. We have therefore chosen to make our fixing parts in a rigid plastic heavily loaded with fiberglass to offer them a longer life than those of soft handles.

The boom is screwed onto webbing reinforcements that go around the central batten to distribute the forces over its entire circumference. This system has already proven itself for many years on our wings with soft handles. The assembly sandwiches the strap for maximum strength and does not allow any twisting.

And the ultimate trick: the screwing nut is a standard nut for US foil box. A smart choice to never find yourself helpless 😉
The boom has an ideal opening angle for your wrist and for a pistol grip which allows you to have a new way of gripping the wing which can be extremely useful in maneuvers, in freeflying or simply on land.

In order to protect the wing from rigid parts, we use Kevlar reinforcements, very expensive materials but which offer incomparable abrasion resistance.

Our spinnaker is made of triple Ripstop throughout the canopy. Firstly because the feeling is much more rigid, firmer. Then because it is the best against tearing without affecting the lightness. Three large diameter fibers reinforce the fabric at regular intervals and in two 90° axes. This mesh strengthens the fabric against heavy shocks and tears.

Our freefly handle has been redesigned to provide more control during your extended surfs or during the most committed surf maneuvers. It’s the small details that make all the difference.
