What Our Gearhead(R) Experts Are Saying: "I've worn the Edge REACTIV Sunglasses for everything from long gravel rides to alpine trail runs, and they've become my go-to pair. The REACTIV lens adjusts fast when moving from bright sun to shaded terrain, so I'm never squinting or overexposed. The frameless build keeps airflow steady and weight low, while the magnetic lens swap system makes changes a breeze when light conditions shift mid-ride."From singletrack descents to sun-soaked road climbs, the Julbo Edge REACTIV Sunglasses give us crystal-clear vision no matter the conditions. Julbo's REACTIV photochromic lens technology automatically adjusts to shifting light, ensuring perfect contrast whether we're in deep forest shade or full midday glare.

When the weather changes, the MagneFix system lets us swap lenses instantly-no fumbling or smudges. Soft Grip Tech temples and adjustable 3D Nose Fit pads lock in comfort and security, even under a helmet. Lightweight, aerodynamic, and built for endurance, the Edge keeps us focused on the trail ahead instead of what's on our face.
