Blocks 95% of all visual light. The only thing darker might be a welding mask...

Julbo's Nomad with mirrored Alti Spectron X6 lenses blocks 95% of transmitted visual light which is ideal comfort when your world of white suddenly turns dazzling bright. The Nomad frame is Julbo's top seller and features removable sun stop shells along the corners for additional peripheral coverage. Keep in mind that Alti Spectron X6 lenses are CE Class 4 protection and not recommended for driving or high-speed situations where changing light (shadows) can suddenly impair your vision.
