Description

Slack was already a vibe, but Slack Cover takes it up a notch—or a few thousand feet. These lightweight, super-comfy sunglasses have removable side and bridge shields that transform them from retro-cool to summit-ready in seconds. The bold double-bridge design keeps you looking sharp, while the SPECTRON HD Polarized lens option boosts contrast, amps up color, and cuts eye strain, so you’re comfortable all day long. Whether you’re hitting high-altitude trails or just rocking the vintage look, Slack Cover has your back—and your eyes.

Product Features
  • Removable Protection: Easily customize your Slack with removable bridge and side shields making them the most protective and customizable sunglasses on the market.
  • Grip Tech Temples: Soft, rubberized temples offer comfort and perfect grip.
  • Curved Temples: Ergonomic profile is comfortable on the face and grips the head.
  • Bio-Sourced Rilsan: Made with materials derived from castor beans, this frame is lighter, stronger and more environmentally friendly than frames made of traditional plastic.

    Great Everyday Pair Of Glasses!

    The style has really grown on me and these glasses have become my go to for day to day life! I have been really impressed by the lens durability. I take care of them as much as I can but, working construction is just really hard on things and there is only a single tiny scratch on one of the lenses which doesn't even show up in my vision. I would definitely recommend!

    Middle Bridge Piece Falls Out

    I really like these glasses. They are comfortable, clear, and perfect for yard work. Unfortunately, after just three days of use, the middle bridge piece popped out and got lost. I checked the spare parts page, but that piece isn’t available yet, and customer service told me I’d have to buy a whole new pair just to replace it.

    The glasses still work, but without the bridge piece, they don’t fit as securely and lose some coverage. I expected better support or replacement options for such a key part. If they offered that piece separately, this would easily be a 5-star product.

    Great coverage

    I like the fit, coverage and weight of these shades. I wore them while teaching a mountaineering course in the Rockies. The Julbo Slack Cover provided exceptional coverage in the bright, snowy environment. Julbo also had great customer service when I needed them to change my order last minute. Two thumbs up to the crew at Julbo

    Function and comfort

    I have worn a lot of sunglasses for endurance sports. these glasses are a perfect fit for days in the mountains on foot or skis, and function well on beach days. Great glass to keep the glare down, side protection to keep out harmful rays and sit firmly on my head. My go to all around adventure sunglasses.

    Great go sensitive eyes!

    I absolutely love these slack cover sunglasses! As someone with sensitive eyes, they’re a game-changer. The blue mirror finish not only provides a stylish look but also effectively reduces glare. The Spectron 4 Polarized HD lenses offer incredible clarity and sharpness, making everything look more vibrant and crisp. They’re lightweight, comfortable to wear for long periods, and truly enhance my outdoor and indoor experience. Highly recommend for anyone seeking both protection and style! I Wish Julbo made a REACTIV 3-4 Polarized HD lenses. And the slack cover sunglasses should be able to get prescription lenses!
