What makes the difference
Back-Zip + Batwing: easy entry, water blocked
You can put it on quickly, even in a windy parking lot. The Batwing acts as a barrier under the zip, limiting water entry when you catch a gust or a slightly submerged waterstart.
Oysterprene Y6: lasting warmth and flexibility
The Oysterprene Y6 foam provides the insulation of a 4/3 without restricting you. Wing movements and waterstarts flow smoothly, even at the end of a session when your forearms are tired.
Well-placed Storm-Dry
The Storm-Dry lining made from recycled polyester covers the upper thighs, belly, and back. You feel the difference on long runs against the wind. Less chill, more time on the water.
Black Diamond: windproof where it counts
Belly and back equipped with Black Diamond. When the wind blows head-on, you stay protected on long runs and between tacks. The only thing flapping is your sail.
GBS + G6 HEAT-ON tape: dry and sturdy
GBS seams (glued and stitched) with interior G6 HEAT-ON tape reinforcements. This limits water entry and lasts over time, session after session.
Finishes designed for riders
Thermo-fused sleeves for a clean wrist, back of the knees shaped for bending without pulling, glue tape at the ends. You move, the suit moves with you.
Wind details that change everything
Velcro at the ankles to manage flow, water outlets at the calves to avoid the permanent puddle, anti-tetanus cut at the forearms. And a key pocket, because going back to the spot without a key... not cool.

Frequently asked questions
What is the closure system of this GURU WIND 4/3 and does it limit water entry?
It uses a Back-Zip complemented by a Batwing, a water barrier under the zip. This combo makes it easier to put on at the spot and reduces water entry during falls, waterstarts, or runs against the wind. You stay drier and lose less heat during the session.
What sports is this suit designed for?
The GURU WIND 4/3 BZ is clearly aimed at wind sports: Windsurf, Kite, and Wing. Details like velcro at the ankles, water outlets at the calves, anti-tetanus cut at the forearms, and Black Diamond protection on the belly and back are designed for these practices.
Where are the Storm-Dry lined areas and the Black Diamond wind protection located?
The Storm-Dry lining made from recycled polyester is positioned on the upper thighs, belly, and back to boost warmth. The Black Diamond protection is found on the belly and back, areas highly exposed to wind during runs and transitions.
How are the seams constructed and what finishes improve comfort?
The seams are GBS (glued and stitched) with interior neoprene tape reinforcements and G6 HEAT-ON tape for durability and waterproofing. For comfort, thermo-fused sleeves, glue tape at the ends, and shaped back of the knees for better bending without pulling.
Is there a key pocket and water drainage features?
Yes, there is a key pocket. To avoid the "bucket at the ankles" effect, the suit includes water outlets at the calves. The velcro at the ankles also helps manage water entry and control flow while riding.
What is the foam made of and what is the thickness?
The main foam is Oysterprene Y6, combined with recycled polyester and nylon coating fabrics laminated to water. The thickness is 4/3 mm, a good compromise between warmth and flexibility for riding when the wind picks up without feeling restricted.
