    Buyer beware: I wanted to love these, and yet...

    This is a two-year review. I've been a repeat Julbo customer for over 14 years...all my sunnies are Julbo: from the Race, to the Rush (my favorite of all), and, as noted, for the past two years, to the Slack. As with all my Julbos, I absolutely love their lenses! Muah...chef's kiss!

    And yet, it's the frames on the Slack that leave a lot to be desired. I loved (yes, past tense) the look of them (more on that in a moment). And I still love that they're so light and comfortable that I hardly notice them while wearing them. That said, they have, in my view, two major flaws. First flaw (and the reason I don't love the look any longer): the thin "second" bridge shatters off so easily if they accidentally hit the ground. The first time I leaned over to pick up something off the ground (about 2 weeks after getting them), they fell off my hat, hit the ground, and the second bridge broke off. So, I super glued it back on. It happened a second time but this time they fell off my face. It broke again and I reglued it on. And then a third time...but this time I couldn't find the bridge. Gone for good. And that, at least for me, significantly changes the look of the glasses. I don't really love how they look any longer. Do I wear them? Sure, but hardly at all unless I have to because I forgot my Rushes. And that's a bummer. Second flaw, which is partly why they're so comfy and also why they fall off so easily: the arms have such little grip to stay put, both on the head and one's hat. The…

    Hi Richard,

    Thank you for taking the time to share such detailed feedback, and we're genuinely grateful for your loyalty as a Julbo customer over the past 14 years. It means a lot that you've trusted us with your eyewear across so many adventures.

    We're thrilled to hear you love the lenses on the Slack — that's something we're really proud of. At the same time, we're truly sorry to hear about the durability issues you've experienced with the frame, particularly with the second bridge breaking off after accidental drops and the arms not providing the grip and stability you need for your active lifestyle in the hills.

    Your feedback about the frame construction and how it's impacted your experience with the Slack is really valuable to us, and we've shared it with our product team as we continue to evaluate and improve our designs. We understand how frustrating it must be, especially when you've had such great experiences with other Julbo models like the Rush.

    We'd genuinely like to help make this right, even though you're outside the standard warranty period. Please reach out to our Customer Support team at info@julbousa.com with your order details — they can take a closer look at what you've experienced and explore what we might be able to do for you.

    Thank you again for your honest feedback and for helping us improve. Your insights from years of real-world use are invaluable.

    I've rocked four pairs of Explorer 2.0. Needed something a little more casual. Enjoy the slack and the Spectron. Hate cheap polarized sunglasses that are so dark you have to stare into the sun to see daylight.

    Great fit with good darkening

    These replaced my previous shades that I dropped on to trim tracks in Italy. I like the fact that when driving they kill the glare but still let me see my cars heads up display. None of my other glasses let me see the display except my other pair of Jublio.
