Water & Waves –
The perfect sunglasses for your water sports

Our Sunglasses are tested in extreme water conditions—big waves, jumps, and intense water impacts. Watersports athletes and professionals evaluate how well they maintain their shape and enhance visibility.

  • Wave Resistance: Our sunglasses withstand even the toughest wave conditions. Testers check if they remain stable and resistant during jumps and intense water movements.

  • Visibility with Water Reflections: We test how well our lenses reduce reflections from water surfaces, ensuring clear vision even in strong sunlight.

  • Saltwater Resistance: Our sunglasses are tested for performance in saltwater. No fogging, no impaired vision—so you can focus entirely on your adventure.

  • Secure Fit for Water Activities: Even with strong water impacts and intense movements, the sunglasses stay securely in place, ensuring that slipping frames don’t affect your performance.

  • Scratch and Sand Resistance: Our sunglasses are designed to resist scratches and wear caused by sand and rough environments, maintaining their functionality and clarity even in challenging conditions.

  • Hydrophobic Lenses: Our lenses repel water, preventing droplets from accumulating on the surface and ensuring clear vision even in rain or splashes. This technology also makes cleaning easier and more effective—water and salt don’t stick to the lenses, keeping them ready for action at all times.

 

Wind & Speed –
Performance Under Extreme Conditions

Our Sunglasses Are Tested Under the Toughest Conditions – High Speeds and Strong Winds

Professional athletes put our sunglasses to the test in action, evaluating their stability and durability at top speeds and in stormy conditions.

  • Wind Resistance: The sunglasses must remain stable and maintain clear vision even at high speeds and in strong wind—without slipping or losing their shape.

  • Temperature Fluctuations: Our sunglasses are tested for adaptability to sudden changes in temperature—from cold to warm environments—without compromising fit or comfort.

  • Resistance to Particle Impacts: Dust, insects, and other airborne particles can be a challenge during high-speed activities. Our sunglasses are designed to protect your eyes while still ensuring a clear field of vision.

  • Clear Vision at High Speeds: At high speeds, our lens technology prevents distortions and glare, giving you sharp and undistorted vision—even in extreme conditions.

  • Helmet Compatibility: Our sunglasses are tested with various types of helmets to ensure a secure and comfortable fit, even during the most extreme maneuvers.

 

Impact resistance & comfort -
Load tests for maximum protection and comfort

In sports that involve fast movements, falls, and collisions, the sunglasses are tested for impact resistance and fit. Professional athletes subject the glasses to intense stress tests and document their experiences to ensure they stay securely in place and provide protection even under extreme conditions.

  • Impact Resistance: Our glasses are tested for their resilience during falls, collisions, and sudden movements. Even in extreme situations, they provide full protection.

  • Stable Fit & Optimal Comfort: The test includes intense movements and extreme maneuvers. The glasses are tested for their fit and hold, ensuring they don’t slip during quick direction changes or jumps.

  • Vibration Resistance: In sports with high vibration intensity, such as mountain biking or racing, the glasses are tested for how well they absorb vibrations and maintain their stability.

  • Sweat Resistance: Even under intense physical exertion, the glasses stay securely on the nose. The test ensures they don’t slip during vigorous movements.

  • Comfort during Intense Activities: The glasses are tested in various scenarios of intense physical activities to ensure they remain comfortable during jumps, quick turns, or abrupt movements.
