Julbo Vermont Classic Spectron 4 sunglasses are legendary glacier eyewear representing Julbo’s alpine heritage. Designed for high-altitude expeditions, they deliver exceptional eye protection in the brightest mountain and snow environments.

The dark Spectron 4 polycarbonate lenses are lightweight, impact-resistant and offer full UVA, UVB and UVC protection. Their very low visible light transmission helps reduce eye fatigue and glare in intense sunlight. Signature leather side shields block peripheral light, while flexible Grip Tech temples provide secure fit during movement.
