Collection: Mountain Glasses with Category 4 Smoke Lenses

MOUNTAIN GLASSES WITH CATEGORY 4 LENSES

An excursion in the high mountains and on the glacier represents complete detachment from the city and total immersion in nature. Mountaineers, hikers, and mountain enthusiasts are constantly seeking technical materials that help them reach the summit and make each excursion unique.

Protecting your eyes adequately is as fundamental as choosing the right shoes or outerwear. In the mountains and at high altitudes, UV rays and sunlight are much more intense due to less shielding from urban smog and the significant impact of altitude.

Using mountain glasses with category 4 smoke lenses is the optimal solution for those planning excursions at high altitudes, on glaciers, and during days with very strong light conditions. The category 4 lens, which is darker than category 3, is particularly suitable for hikers who are sensitive to the strong light typical of mountain environments. This special lens allows the eyes to remain relaxed throughout the entire excursion, even in extreme lighting conditions.

Mountain glasses with category 4 lenses are commonly used for extreme expeditions such as Everest, K2, and peaks above 4,000 meters. Due to the type and darkness of the lens, these glasses help prevent constant glare from intense light conditions. Additionally, at high altitudes, the reflection of snow disperses light rays upwards.

The category 4 mountain lens can also be used for excursions at lower altitudes as additional eye protection. They provide a greater sense of relaxation for the eyes compared to category 3 lenses, especially during prolonged use.

Technical Characteristics of Mountain Glasses with Category 4 Lenses:

Protection from UV Rays and Optimal Vision: Category 4 mountain lenses are designed for mountaineering and are now also used for hiking at lower altitudes because they are very restful for the eyes, even in the strong light conditions typical of mountainous regions. The lenses are equipped with anti-fog treatment, making them particularly suitable for mountaineers who are sensitive to intense light, which often makes it difficult to see the route. Choosing this special lens is equivalent to a guarantee of fully enjoying your excursions.

Unbreakable Lens: All mountain glasses with category 4 lenses are constructed with anti-break polycarbonate lenses. Polycarbonate is the ideal material for technical lenses in mountain environments due to its safety features. In the event of an accidental impact, the lens does not shatter into harmful fragments; instead, it distributes the shock across the entire surface, creating a spider web effect that renders the lens unusable.

Ultralight Frames: All mountain goggle frames with category 4 lenses are made of TR90, a special composition of nylon and carbon fiber that makes the glasses 20% lighter than conventional materials. This material is more resistant to high and low temperatures, as well as to impacts and mechanical stress. TR90 is hypoallergenic, allowing for extended wear without skin irritation. The rubberized parts are crafted from soft Megol, which is also hypoallergenic. This enhances comfort and features Grip technology to increase stability on the face.

Technologies: Some models of mountain glasses with category 4 lenses are equipped with specific technologies that enhance their performance. It is important to carefully choose the model based on your needs to fully utilize the available technologies.

The OUTDOOR and MAKALU models come equipped with a sweat sponge made of soft hypoallergenic material. This feature prevents light from filtering in laterally and protects the eyes from dust, insects, and leaves. Additionally, it provides warmth in cold conditions. All three models include a removable elastic cord to enhance the grip of the glasses on the face.

All items are delivered in a hard case to provide added protection for the glasses when placed in a backpack.
