Test REACTIV Technology at UTMB!

Taking part in one of the UTMB races? Take advantage of your race to test REACTIV technology directly on the trails, in real race conditions.

Stop by the Julbo booth at the UTMB Expo before your start, pick up your pair of sunglasses, and put them to the test throughout your race as you take on the legendary trails around Mont Blanc, crossing alpine passes and breathtaking mountain scenery.

Experience the performance of photochromic lenses that instantly adapt to changing light conditions—from shaded forest sections to bright snowfields and exposed ridgelines—for optimal visual comfort in every condition.

📍 Pick up your pair* at the Julbo booth at the UTMB Expo during the following opening hours:

• Monday 24: 10:00 AM – 6:00 PM

• Tuesday 25: 10:00 AM – 6:00 PM

• Wednesday 26: 9:00 AM – 6:00 PM

• Thursday 27: 9:00 AM – 6:00 PM

• Friday 28: 9:00 AM – 2:00 PM

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

Test REACTIV technology where it matters most: 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.
