Test the REACTIV technology at the Marathon du Mont-Blanc!

Taking part in one of the Marathon du Mont-Blanc races? Take advantage of your race to test REACTIV technology directly on the trails, in real conditions.

Stop by the Julbo booth at the Trail Camp before your start, pick up your sunglasses, and test them throughout your race. From the technical trails of the Chamonix Valley to the high-altitude panoramas facing the roof of Europe, experience the performance of photochromic lenses that instantly adapt to changing light conditions: shaded forest sections, bright snow, exposed ridgelines — for optimal visual comfort in all conditions.

📍 Pick up your pair* at the Julbo booth at the Trail Camp, Place du Mont-Blanc:

• Thursday, June 26: 9:30 AM – 7:00 PM

• Friday, June 27: 9:00 AM – 7:00 PM

• Saturday, June 28: 9:00 AM – 7:00 PM

👉 Come meet us at the booth and experience REACTIV in the heart of the race!

Test REACTIV technology where it truly matters: in the middle of the effort, out on the trails.

*A credit card imprint will be required when borrowing the sunglasses. No charge will be made unless the sunglasses are not returned.
