What makes the difference
Targeted warmth with Storm Dry
The Storm Dry lining covers the thighs, belly, and back. You feel the temperature rise from the first runs, and it stays stable when the wind picks up. Recoveries after a long waterstart are less “brrr” and more “go”.
Windproof front/back
The Black Diamond panel at the front and back acts like a windshield. Gusts hit you less, transitions remain clean. Useful when you’re heading upwind in gusts and the torso takes it all.
Oysterprene flexibility
The Organic Oysterprene foam (certified USDA 63% bio-based) provides natural flex. Torso rotations for trimming/letting out happen without straining the shoulders. By the end of the session, your arms will thank you.
Back zip that doesn’t slow you down
Back Zip = quick entry in the parking lot, even with a bit of wind playing with the towel. You pull, adjust, and go. Less hassle, more ride.
Seams ready for long sessions
GBS (glued and blind stitched) assembly with internal tape. Tight and clean feel, less water entry when you fall in the lulls between gusts. The only thing dripping is your nose after take off.

Frequently asked questions
What type of zip does this suit have, and is it easy to put on?
The GURU WIND 5/4 is equipped with a Back Zip (rear zip). You open wide, slide your shoulders in without forcing, and close in two seconds. Handy in a windy parking lot or when you’re chaining sessions and want to get back out quickly without fighting with the suit.
Is it suitable for cable wake at the park?
The brand's recommended use is focused on wind sports (windsurfing, kitesurfing, wingsurfing). For pure cable/park use, you can compare with other 5/4s in the “5/4 Men's Full Suit” category that are more geared towards continuous pull riding and without windproof panels.
What thickness and for what conditions?
It’s a 5/4 mm: 5 mm on the core for warmth, 4 mm on the mobility zones. In practice, it’s your suit for cool to cold sessions in wind, kite, or wing, when you want to keep flex without sacrificing insulation, especially with the windproof panels front/back.
What are the areas lined with Storm Dry?
The Storm Dry lining is positioned on the thighs, belly, and back. The idea is to concentrate the temperature rise where you take the wind and water, to stay operational between waterstarts and during long upwind runs.
What is the composition and material commitment?
The foam is made of Organic Oysterprene (natural rubber + oyster shell powder). Announced composition: 80% natural rubber, 9% recycled polyamid, 6% polyamid, 3% elastane, 2% polyester. The suit is certified USDA 63% bio-based.
What sizes are available?
Sizes listed by the manufacturer: S, MS, M, MT, LS, L, LT, XLS, XL, XXL, and 3XL. Choose according to your usual measurements for a men's fit. If you’re between two sizes, aim for the fitted one to limit water entry without restricting your mobility.
