Sooruz Guru Pro 4/3mm Men's Fullsuit Chest Zip - Black

The Soöruz GURU PRO 4/3mm is the definitive high-performance wetsuit for riders who refuse to compromise on stretch, warmth, or environmental responsibility. As the top-of-the-line model in the Soöruz range, the Guru Pro is designed alongside pro riders to be as light and flexible as possible. It features the revolutionary Örganic Oysterprene Ö8 foam, a sustainable alternative to petroleum-based neoprene made from natural rubber and recycled oyster shell powder. This bio-sourced foam delivers exceptional insulation and "second-skin" mobility, making it ideal for high-intensity sessions in UK waters.

Innovation continues with the Storm-Dry recycled polyester inner lining, strategically placed on the abdomen, back, and upper thighs to provide superior heat retention and lightning-fast drying times. The exterior is reinforced with Soöruz's exclusive Black Diamond material on the back—a flexible, windproof, and water-repellent coating that protects against wind chill without sacrificing agility. With its chest-zip entry to minimize water flush and a 3-year warranty on seams, the Guru Pro 4/3mm is a premium, eco-conscious choice for surfers, wing foilers, and kitesurfers seeking peak performance during the UK's mid-season and summer months.

Expert Advice: The Guru Pro 4/3mm is our favourite "quiver-killer" for the UK season. While most brands use limestone, Soöruz's Oysterprene feels noticeably more supple, which is a game-changer when you're on your third hour of winging or surfing. The Black Diamond panel on the back is particularly effective on the UK's East Coast or during punchy Atlantic sessions where the wind chill can bite even when the sun is out. If you’re between sizes, the MS (Medium Short) and MT (Medium Tall) options ensure a tailored fit that prevents the "pooling" of water, keeping you warmer for longer.
