Alpina Skywalsh - Cat 4

Designed for serious alpine objectives and harsh high-mountain conditions, the Alpina Skywalsh delivers uncompromising glacier-grade protection for mountaineers and climbers who demand dependable performance above the snowline. Combining modern glacier-glass styling with category 4 protection and full side coverage, these technical mountain sunglasses are built to handle intense sunlight, reflected glare and exposed environments where standard eyewear simply won’t cope. From glacier crossings and mixed alpine routes to long summit days in bright snow conditions, the Skywalsh is engineered for high-altitude performance.

The category 4 Ceramic lenses provide maximum protection against extreme brightness commonly encountered on glaciers and high peaks, while also offering 100% UV-A, UV-B and UV-C protection. Multiple mirror coatings help reduce harsh glare and reflected infrared light from snow, ice and rock, helping minimise eye fatigue during long days in exposed terrain. The shatter-resistant ceramic lens construction adds an extra layer of security in technical mountain environments.

Integrated side shields prevent stray light from entering around the lenses — an essential feature for mountaineering and glacier travel where reflected UV exposure can cause serious eye damage. The strongly domed lens profile also improves peripheral protection from wind, spindrift and cold mountain air without compromising visibility. Mountain communities frequently highlight the importance of full side coverage and dependable anti-fog performance during alpine and winter climbing conditions.

Fogstop coating on the inside of the lens helps maintain clear vision during high-output ascents and rapidly changing temperatures, while the hydrophobic outer lens treatment repels water, snow and dirt to keep visibility sharp in unpredictable weather. Decentered lens technology ensures distortion-free optics, helping improve clarity and reduce visual fatigue during technical movement and route finding.

The lightweight yet highly durable TR90 frame construction balances robustness with long-lasting comfort. Soft rubberised nose pads and temple tips provide a secure fit during technical climbing, scrambling and long approaches, while the stable two-component frame design keeps the glasses comfortable even during extended wear at altitude.
