Julbo Ultimate Spectron 3 HD Sunglasses - Black/Purple Frame, Grey Flash Lens, Cat. 3

Unlike typical sport sunglasses that trap heat and fog up on steep climbs, the Julbo Ultimate features a full-ventilation frame that keeps air moving behind the lens. Built for high-output mountain days, it pairs a featherlight Grilamid TR90 frame with helmet-compatible temples, eliminating pressure points and ensuring clear vision when every move counts.

• Spectron 3 HD lens: grey polycarbonate with flash coating, Category 3 protection, 12% visible light transmission
• 100% UVA, UVB, and UVC protection for complete eye safety at altitude
• Full venting frame design prevents fog during intense effort
• Grilamid TR90 frame: lightweight, flexible, and impact resistant
• 3D Nose Fit adjustable nose pad for a custom, secure bridge fit
• Grip Tech temple tips with non-slip texture keep the frame stable
• Helmet-compatible temples for seamless integration with climbing, cycling, or ski helmets
• Unisex standard/large fit with generous lens coverage: 133 mm wide, 50 mm high

In daily use

On a bright ridge traverse or a fast descent, the Julbo Ultimate keeps your vision crisp and your eyes protected. The Spectron 3 HD lens cuts glare without distorting contrast, so you can read terrain changes and trail details. The full venting system allows air to flow behind the lens, reducing fog when you stop or breathe hard. The adjustable nose pad and Grip Tech temples hold the frame securely, even when you're sweating or moving over rough ground.
