Demon Altavia sunglasses mountaineering

The technical Altavia sunglasses by Demon are the ultimate choice for those facing extreme environments in high mountains, where comfort, protection, and reliability cannot be compromised. Designed to meet the needs of mountaineers and outdoor enthusiasts at high altitudes, Altavia offers total protection thanks to an ergonomic and enveloping design, crafted to completely shield against wind, dust, debris, and peripheral light, improving visibility even in the presence of snow or ice. The category 4 polycarbonate lenses, ultra-lightweight and shatterproof, ensure maximum shielding from intense UV rays, blocking up to 95% of visible light and preventing issues such as photoconjunctivitis or snow blindness. The frame is made of TR90, an innovative material based on nylon and carbon fiber, which guarantees mechanical resistance, flexibility, shape retention against thermal excursions, and a weight reduction of 20% compared to traditional materials, reducing fatigue even after long hours of use. The support system includes an adjustable elastic for a stable and secure fit, designed for dynamic activities such as mountaineering, trekking, and skiing. Additionally, the Altavia model is compatible with prescription lenses, making it ideal for those who need vision correction without sacrificing extreme protection. The carefully designed dimensions (width 138 mm, height 52 mm, temple length 126 mm, lens base 6) ensure a comfortable fit on various face shapes. Altavia is not just a simple pair of sunglasses, but a true technical tool designed for those who live the mountain with intensity and seek a reliable ally to face the most difficult conditions. With Demon Altavia, every peak is closer, with the assurance of clear, protected, and comfortable vision.
