SOORUZ - GURU WIND 4/3 BZ Fullsuit in Organic Oysterprene - Men
When the wind picks up and the water gets choppy, you stay focused. The GURU WIND 4/3 BZ follows you without pulling your arms or freezing your back.
Ready for windy sessions that last long
A 4/3 designed for wind, kite, and wing: warm on the torso, flexible at the joints, and especially well protected against the wind. You rig up, take your first run, and even at the end of the session when it calms down, the warmth stays locked in.
What makes the difference
Back-Zip + Batwing
Easy to put on at the spot, then the Batwing panel limits water entry in the back. Handy when you take a good crash at the jibe and the water wants to join in.
Oysterprene Y6
Foam made from crushed oyster shells. Flexible under the shoulders, responsive when you pump the wing. The flex stays clean even while chaining runs.
Black Diamond windproof
In the front and back, this coating blocks wind gusts. You feel it especially when planning, when the air is cold and you pick up speed.
Storm Dry 2 in the right places
On the upper thighs, belly, and back, the lining retains heat and dries quickly between sessions. Coffee break, you re-gear, and off you go.
GBS seams + Full G6 HEAT-ON tape
Sewn/glued and reinforced inside. Less water entry, more durability. The only thing leaking is the time spent in the parking lot.
Wind/kite/wing specific details
Velcro at the ankles, water drainage at the calves, anti-cramp cut for the forearms. When it pulls hard at the harness, you keep your energy.
Secure key pocket
Pocket with lycra gusset and elastic loop. You stash it, forget it, and ride.

For which rider?
For the one who chains runs when it’s blowing, who jibes, who jumps, and who wants to stay warm without losing mobility. If your thing is to harness the gusts rather than endure them, this 4/3 will give you the comfort to push a foil, hold the sail, or send a clean loop without cramping up.
Frequently asked questions
Is the GURU WIND back-zip or chest-zip?
This model is back-zip, with a Batwing panel to limit water entry in the back. If you prefer a chest closure, check out the SOORUZ - 4/3 CZ GURU PRO Fullsuit - Men in OYSTERPRENE Bio, which offers a chest zip approach.
What sports is this suit designed for?
According to specifications, the GURU WIND 4/3 BZ is developed for windsurfing, kitesurfing, and wing. Everything is oriented for these practices: cut of the forearms, water drainage at the calves, Velcro at the ankles, and windproof coating on the front and back.
Is it suitable for cable wakeboarding?
This version is designed for wind, kite, and wing. For cable use, we recommend more generalist models from SOÖRUZ, like the SOORUZ - 4/3 BZ FIGHTER Fullsuit Men in OYSTERPRENE. You will find other options in the 4/3 Men’s Fullsuit category.
What are the key features against cold and wind?
The Black Diamond coating on the front and back blocks the wind, the Storm Dry 2 lining on the belly, back, and upper thighs retains heat, and the GBS seams with Full G6 HEAT-ON tape reinforcements limit water entry to stay warm longer.
Is there a pocket for keys?
Yes, the suit includes a key pocket with a lycra gusset and elastic loop (according to the dealer sheet). Ideal for keeping your key secure during the session, without worrying in the parking lot.
How to maintain it for longevity?
Rinse with fresh water after each session, drain it, and dry it in the shade, flat or on a thick hanger. Avoid hot water, machine, dryer, and long sun exposure. Clean and dry storage prolongs the flexibility of the foam and the effectiveness of the seams.
