Description

Unrivaled Protection at Altitude: Engineered for the World’s Harshest Environments.

The Glacier Shield is uncompromising performance gear, built not just to block the sun, but to conquer extreme light conditions. Designed specifically for mountaineering, high-altitude trekking, snow sports, and glacier crossing, these sunglasses provide the crucial protection required where UV intensity is at its highest and reflected light is blindingly amplified. If you are venturing above the tree line or into vast snow fields, the Glacier Shield is your non-negotiable optical safeguard.

Category 4: Maximum Light Reduction

The defining feature of the Glacier Shield is the inclusion of Category 4 (Cat. 4) lenses. These are the highest category of sunglasses available, offering extreme light reduction (transmitting only $3\%$ to $8\%$ of visible light). This is essential for preventing snow blindness and severe eye fatigue in environments where light is reflected from snow and ice. Note: Due to their darkness, Cat. 4 lenses are not suitable or legal for driving. They are strictly for intense, high-exposure outdoor use.

Peripheral Glare Elimination

A unique and crucial feature is the inclusion of removable leather or robust rubber side shields. These shields wrap around the temples, eliminating peripheral light entry, a common source of glare and eye strain in wide, open environments. They also provide essential protection against wind, dust, and debris that are common in mountainous and desert terrains. The shields snap securely into place but can be easily removed when you return to lower, less intense light conditions.

Rugged, All-Weather Construction

The frame is constructed from a durable, flexible Grilamid TR90 composite that maintains its integrity and shape even in freezing temperatures. The wrap-around ergonomic fit ensures total coverage and security. We’ve integrated an adjustable elastic strap that can be attached to the temple tips, guaranteeing that your crucial eye protection remains secure during falls or rapid movement. Vented frames are included to ensure airflow, dramatically reducing the risk of lens fogging during strenuous climbs or shifts in temperature.

Core Safety and Performance Features:

• $100\%$ UV Protection: Total defense against UVA, UVB, and UVC radiation.

• Anti-Scratch Coating: Lenses treated to withstand the rigors of mountain conditions.

• Rubberized Nose Bridge: Enhanced grip to prevent slipping when wet or sweaty.

The Glacier Shield is professional-grade equipment for serious adventurers. It is an investment in your safety and success when confronting the world’s most formidable landscapes. Never compromise on optical protection when challenging the extremes.
