At altitude, UV radiation increases significantly with every hundred metres of elevation gain. On snow and open water, reflective glare compounds the problem. Quality outdoor sunglasses aren't a style choice — they're protective equipment. The sunglasses at Mountex are sourced from optical brands with serious outdoor credentials: polarised lenses for glare reduction, category 3 and 4 UV protection for high-altitude and glacial environments, and frames built to stay on your face when the conditions get demanding.
