For you, high-alpine mountaineering is just as much about the physical experience as it is the rocky, snow bespotted peaks and thanks to the newly redesigned Julbo Explorer REACTIV Sunglasses, you're able to view your craggy companions in comfort. Constructed with a more ergonomic fit, better ventilation, and a more slim silhouette, the Explorer REACTIV features full spectrum protection, adjustable temple arms, and removable side shields for an entirely customizable experience. Additionally, the Explorer is equipped with Julbo's REACTIV lenses, which are polarized, photochromic, and anti-fogging. This combination of lens technology provides 100% protection from the sun's harmful UV rays and also adapts with the ever-changing environment--meaning shadows, highlights, and contrasts are enhanced rather than dulled. Not to mention, the Explorer is fashioned with a panoramic design that offers an unimpeded view, while the front ventilation and anti-fog coating assures that the build-up of body heat won't get in your way.
