Vallon Heron Glacier Sunglasses Off/White, One Size

What Our Gearhead(R) Experts Are Saying:"I wore the Heron Glacier Sunglasses on a multi-day ski touring trip above the snowline and they handled conditions I've historically struggled with. The Cat. 4 lens blocks an intense amount of light without losing contrast, and the leather side shields make a real difference on exposed ridgelines where the glare comes at you from every direction."Above the treeline, where the snowpack stretches unbroken in every direction and the sun reflects off every surface at once, standard sunglasses simply are not enough. The Vallon Heron Glacier Sunglasses were engineered for exactly those conditions, bringing Cat. 4 polycarbonate lenses with a mirror coating and anti-fog treatment that handle the most intense light environments on the planet without compromise. At just 25 grams, the TR90 Grilamid frame disappears on the face while fully adjustable stay-on temples keep everything locked in through long days of ski touring, glacier travel, and high-altitude climbing. Genuine leather side shields wrap the eye area completely, eliminating the peripheral light exposure and wind that open-frame sunglasses leave unaddressed on exposed terrain. The detachable centrepiece and side shields give you the flexibility to configure protection to match the day's conditions, whether you're navigating a crevassed glacier or descending into calmer terrain below. Every pair supports one kilogram of plastic cleanup, because the mountain environments these were made for are worth protecting.
