Julbo Frequency Reactiv (medium fit)

Robust, durable, ultra lightweight sport glass with a wide lens surface for a panoramic view. The Reactiv lenses are photochromatic and get darker or lighter to match changing light conditions, from overcast to bright sun. Response time is quick and not affected by temperature - these are great for cold weather nordic skiing to summer cycling. The lenses are coated for anti-fog and oil-repellency properties, and are vented in the front for air flow. The nose and temples are grippy and won't stick to your hair.

Photochromatic lenses: Category 1-3 (visible light transmission rate: 13% - 72%)
What's included: glasses, soft storage bag, semi-firm zip case
