Change is good, and according to Julbo, nowhere is that statement truer than in the category of glacier glasses. As one of the original pioneers of glacier glasses at the end of the 19th century, Julbo could have remained satisfied with the near mythic status the Vermont achieved. Instead, the company continued to innovate, and the Explorer 2. 0 Sunglasses with Spectron 4 Lens were born. If you're mapping out a trek to the Haute Route or Ranier, the Fitz Roys or Everest, invest in this thoroughly modern take on a mountaineering essential to be fully prepared. Replacing the traditional leather shields might've been a controversial decision, but Julbo had good reason for it. The Explorer's synthetic side shields are removable and not nearly as susceptible to damage after spending long periods of time in wet weather as leather. As you spend days navigating unpredictable glaciers, the Explorer's wraparound design and anti-reflective Spectron 4 Lenses do an even better job at blocking light from all angles than its predecessor, while its fully adjustable temples retain the same nearly limitless customization options as the Vermont for all-day comfort and healthy, safe eyes.
