Sunglasses Julbo Shield Reactiv 2-4 DL Bleu — black/black, photochromic lenses

Julbo Shield Reactiv 2-4 DL Bleu — black/black are mountain sunglasses designed as a full-coverage shield with photochromic Reactiv 2-4 lenses that adjust to changing light conditions. The one-piece shield shape and wraparound frame deliver broad face protection from sun, wind and glare, while the Reactiv lens technology provides a variable tint range suitable for mixed alpine environments. The black frame with black shield offers neutral color and minimal reflections for outdoor activities where uninterrupted vision and eye protection are required.

Advantages

The shield construction ensures continuous peripheral coverage and reduces light intrusion from above and the sides. Reactiv 2-4 photochromic lenses automatically darken in bright sunlight and lighten in lower light, improving contrast and comfort across a wide range of alpine conditions. The wraparound fit is compatible with helmet use and helps shield the eyes from wind and debris. The black finish minimizes distracting reflections and maintains a discreet appearance during technical outdoor use.

Suitable for

• Day hiking and trekking in variable weather
• Mountaineering and glacier travel where high UV protection and coverage are needed
• Alpine approaches and exposed ridgelines with changing light
• High-contrast outdoor activities such as snowfields or rocky terrain

Key specifications

• Lens type: photochromic Reactiv 2-4 (variable tint)
• Frame style: full-coverage shield, wraparound design
• Color: black frame with black shield
• Intended use: mountain and alpine environments
• Protection: broad coverage from sun, wind and peripheral glare

How to use

Put the sunglasses on so the shield sits comfortably across the brow and provides full peripheral coverage. Use them outdoors in changing light conditions; the Reactiv 2-4 lenses will adapt automatically between darker and lighter tints. When worn with a helmet, check that the frame does not interfere with headgear and adjust position for a stable fit. Clean lenses with a soft microfiber cloth and rinse with clean water if abrasive particles are present before wiping.

Usage recommendations

For optimal protection in alpine and glacier settings, combine the shield sunglasses with a brimmed hat or helmet and use additional eye protection if performing activities with high particulate or reflective glare. Store in a protective case when not in use to preserve lens performance and mechanical condition.
