Heron Mountain is a more versatile version of our glacier glasses. The main difference between the two is that Heron Mountain has a category 3 lens that lets through 12% of visible light (as opposed to 6% for Heron Glacier). For general outdoor activities like skiing, ski touring, and hiking this is more than enough. It is also beneficial for overcast and darker conditions.
The frame is made from Swiss-invented TR90¬ß polyamide. The sunglasses are therefore incredibly lightweight and comfortable. The brown-tinted lens is optimal for snow as its warm perception enhances contrasts. The 2mm thick polycarbonate lens is shatterproof for added safety. The leather side shields protect the eyes from side glare, while the anti-fog coating is applied to prevent condensation. Heron Mountain is truly the ultimate all-around sunglasses for the mountains.
