With its unique semi-rimless design, Crux offers unobstructed vision, enhanced ventilation and lightweight comfort. The upper frame maintains the integrity of the lenses with minimal added weight. Choose from two different lens shapes for a perfect fit and optical performance.
Serilium Lenses-
Serilium is a polycarbonate material that offers unrivalled clarity in a lightweight yet exceptionally strong lens. This impact-resistant material stands up to high-velocity impacts from objects like flying gravel.
Anti-reflective coating-
Eliminates any light that bounces off the inside of the lens.
Element Shed- Ensures that virtually all moisture, dirt and oil will roll right off the surface of your lens- keeping them cleaner, longer.
Revo high contrast polarisation – polarised light, commonly known as glare, is the bright light that’s reflected off surfaces like water, snow and ice. High contrast polarisation blocks this glare and selectively filters light so you see clear, vivid and natural colours.
Motion fit- Our motion-fit system is a patented frame design that precisely positions your sunglasses to ideal locations on your nose and ears, you’ll experience a comfortable fit that’s free of unwanted pressure points.
Open-edge lens design – Excellent for most sport applications, open-edged lenses create unobstructed views, enhanced ventilation, and reduced fogging.
Eco-Use – Eco-Use is a nylon frame material made in part from the seed of the castor bean plant. Not only is this material sustainable and more environmentally friendly, it is also exceptionally light and flexible.
Nylon Frame- Highly durable, lightweight frames made from Eco-Use or Re-Use materials. Ideal for a variety of uses ranging from sports and performance optics to everyday wear.
Stem Stock/Pads – Stem socks and stem pads increase grip to provide a snug, secure fit when active.
