ALTAVIA Category 4 Mountaineering Sunglasses

ALTAVIA is designed for high-altitude mountaineering, hiking and demanding mountain environments, where intense sunlight and strong reflections from snow and ice require a higher level of light protection. Its Smoke Category 4 mirrored lenses are combined with a lightweight TR90 frame, wraparound geometry and removable side shields to reduce peripheral light exposure and provide greater coverage in exposed conditions. At just 22 grams, ALTAVIA combines technical protection with a lightweight feel for long days in the mountains.

Category 4 Designed for extremely bright light conditions in high mountains and on snow.
22 grams Lightweight construction designed for prolonged outdoor use.
TR90 frame Lightweight and flexible material suitable for active mountain use.
Side protection Removable side shields help limit peripheral light exposure.
Built for exposed environments

Mountain protection beyond a conventional pair of sunglasses

At altitude, the eyes are exposed not only to direct sunlight but also to strong reflected light from surfaces such as snow and ice. ALTAVIA addresses these conditions through a combination of Category 4 lenses, wraparound coverage and removable side shields.

The frame follows the face closely to reduce unwanted light entering from the sides, while the lateral shields extend coverage around the peripheral area. They can also be removed when this additional level of side protection is not required.

This construction makes ALTAVIA particularly suited to users looking for technical mountain sunglasses with a more protective geometry than conventional everyday eyewear.

Why the wraparound design matters

In exposed mountain environments, light can reach the eyes from several directions. The curved Base 6 geometry and side shields help provide broader coverage around the face, contributing to visual comfort when moving through bright and reflective terrain.

Lens technology

Category 4 lenses for intense high-altitude light

ALTAVIA uses Smoke Category 4 mirrored lenses, developed for environments where sunlight and reflected light can become particularly intense. Category 4 lenses provide stronger visible-light shielding than lower lens categories and are especially appropriate for high mountains, snow-covered terrain and glacier environments.

The smoke tint helps maintain comfortable vision in very bright conditions, while the silver mirror finish adds a reflective external surface suited to the technical character of the model.

Very bright conditions

Category 4 filtration is intended for situations with exceptionally high levels of visible light.

Snow and ice

Designed for environments where reflected light from bright surfaces can significantly increase visual discomfort.

Important

Category 4 lenses are very dark and are not suitable for driving.

Lens construction

Polycarbonate lenses for active mountain use

The ALTAVIA lenses are made from polycarbonate, a material widely used in sports eyewear because it combines low weight with good resistance to impact and fragmentation.

For activities such as mountaineering and hiking, where equipment may be exposed to accidental knocks, frequent handling and changing terrain, this construction offers a practical balance between protection, durability and comfort.

Frame & comfort

Lightweight TR90 frame with removable side shields

TR90 construction

The frame is made from TR90, a lightweight and flexible material commonly used for technical sports eyewear. Its flexibility and resistance to mechanical stress make it well suited to active outdoor use.

22-gram weight

ALTAVIA weighs just 22 grams, reducing unnecessary load on the face during long periods of wear on trekking routes, mountain approaches and high-altitude activities.

Removable side shields

The lateral protectors help reduce light entering from the sides of the frame. Their removable design allows the eyewear configuration to be adapted according to the environment and the level of side coverage required.

Base 6 geometry

The Base 6 lens curvature provides a sporty, curved profile that supports the wraparound character of the frame without using the more extreme curvature found on some highly wrapped sports models.

Prescription option

Compatible with directly fitted prescription lenses

ALTAVIA can be fitted with prescription lenses directly into the frame. This makes the model an option for users who require vision correction and want to use a dedicated mountain frame rather than relying on a separate optical insert.

Because prescription requirements vary considerably according to correction, lens design and intended use, the final lens configuration should be selected according to the individual prescription and optical needs.

Recommended use

Designed for demanding mountain activities

ALTAVIA is developed for outdoor environments where high levels of light, reflected glare and prolonged exposure make more protective eyewear particularly valuable.
