This model is primarily made from a plant-based material derived from castor beans.

We use Rilsan®, a high-performance material known for its lightweight feel, flexibility, and durability. It helps reduce the use of fossil-based materials while maintaining the technical standards you expect from a Julbo frame.

More responsible. Just as high-performing.

SPECTRON lenses deliver precise and consistent sun protection. Available in category 3 or 4 depending on the model, they efficiently filter light with a stable protection level that does not vary.

Made from polycarbonate, they are lightweight and impact resistant, perfectly suited for outdoor activities as well as everyday wear. They ensure 100% UV protection and clear vision, even in bright light.
