What Our Gearhead(R) Experts Are Saying:"I wore the Heron Desert Sunglasses on a long exposed day out in serious wind and blowing dust and they performed exactly as advertised. The leather side shields block out light and debris from every angle, and at 25 grams I honestly forgot they were on my face for most of the day."Some environments demand more from your eyewear than a standard lens and frame can deliver, and the Vallon Heron Desert Sunglasses were engineered specifically for those conditions. Genuine leather side shields wrap the eye area to block wind, dust, and sand from every angle, while the Cat. 3 polarized polycarbonate lens cuts through intense desert light with 100% UV400 protection and an anti-fog coating that keeps your vision clear when the temperature swings. The TR90 Grilamid frame weighs just 25 grams and features fully adjustable stay-on temples, so the fit stays locked in through long days of movement without ever feeling like a burden. The detachable leather centrepiece and side shields give you the flexibility to adapt the configuration to the conditions at hand. Every pair also contributes to one kilogram of plastic cleanup, making the Heron Desert Sunglasses a considered choice for the environment you are out there exploring.
