Sunglasses Julbo Slack Cover — green frame, model 641908, cover lens protection

Julbo Slack Cover sunglasses in green frame (model 641908) are sport-oriented eyewear designed for outdoor and mountain activities. The close-fit shape and integrated cover protection provide mechanical shielding for the lenses and additional coverage at the temple and brow line. Constructed to combine glare control with ventilation, these sunglasses suit active use where sun, wind and debris require reliable eye protection.

Advantages

The Julbo Slack Cover delivers a compact, wraparound fit that minimizes light intrusion while maintaining good peripheral vision. Integrated cover protection increases mechanical resistance to impacts and prevents stray light from entering around the lenses. Ventilation details reduce fogging during sustained aerobic activity, and the lightweight frame supports prolonged wear without excessive pressure. The green frame provides a neutral color that pairs well with outdoor clothing and equipment.

Suitable for

• Day hikes and alpine approaches
• Trail running and fastpacking
• Mountain biking on mixed terrain
• Outdoor work where eye debris protection is required

Key specifications

• Frame color: green
• Fit: close-fit / wraparound

How to use

Position the sunglasses so the frame sits comfortably on the nose and temples, ensuring the cover protection aligns with the brow and temple areas for optimal shielding. Adjust any temple or nose details for a secure fit during movement. Clean lenses with a soft microfibre cloth and mild lens cleaner; avoid abrasive materials or solvents. Inspect the cover elements and vents regularly for dirt and clear them to maintain ventilation performance.

Usage recommendations

Use these sunglasses during activities with strong sun exposure, wind or airborne debris. For extended high-altitude exposure, combine them with a brimmed hat for added glare reduction. Store in a protective case when not in use to protect the integrated cover and lens surface.
