    Sporty Alpine Glasses

    • Familiarity: I've used it several times

    These are my go to glasses on single touring days. They have a pretty descent shield, but I do not use them if I am on multi-day expeditions. They are nice and sporty.

    Great glasses; Not so great side shields

    • Familiarity: I've used it several times
    • Fit: True to size

    The glasses are top-notch. I tend to have very sensitive eyes and these shades impressed me with how comfortable they are on my eyes. They're great in the backcountry yet stylish enough to use while out on the town on a hot summer day.

    Only downside is the flimsy side-shields. They fall out easily and it's way to easy to lose them without realizing it. In fact, I lost one of the shields within a month of purchase!

    Better style than Julbo Sherpas

    • Familiarity: I've used it several times
    • Fit: True to size

    Do not look like you just walked out of a drum circle. I needed some glacier glasses and was unsure whether to purchase the Montebianco or Sherpas. Very happy I went with the Spectron 4 lens and Montebianco's. I have worn spring skiing in Utah as well as the Cascades.

    Quality: Julbo makes great quality eyewear. The feel of the glasses, the case they come in and cloth they come with hint at the thought and effort Julbo put into making these glasses.

    Fit: I have a medium face and find the Montebianco's to be a tad big in face for my liking...but I think that is the point. They are comfortable with no pressure points, which is key when you are wearing them for 8+ hours a day.

    Lens: Nice and dark, but will not hinder when some light clouds roll in.

    Performance: Wow! I was completely blown away my second time wearing these. Now I had used them before for a spring day ski touring in the Wasatch mountains here in Utah, so was familiar with what to expect as far as tint. But when 2/3's of the way up Shasta, it is sunny with 50+ mph winds a lot of snow is blowing around. These glasses let in wind, no snow. I love it.

    Do the Job

    • Familiarity: I've put it through the wringer

    Bought these for a trip to Chamonix/Haute Route. Very bright days were no problem with these glasses. Had minimal fogging issues, block wind better than expected. I thought they would be useless in low light, but actually perform better than expected. Highly recommend.

    Hard to beat.

    • Familiarity: I've put it through the wringer
    • Fit: True to size

    Owned a pair of the Montebianco for two years. I wear them all the time on the snow & water where conditions can be extreme, and these Julbos give my eyeballs the relief they need from the brights.

    Good fit and excellent lens quality.

    Also have a "not funky" looking style unlike many other mountaineering glasses, so if you happen to stumble into the streets or a restaurant wearing them, you won't look outlandish.

    Proving durable so far too.

    What's not to like?

    Great simple glacier glasses

    • Familiarity: I've used it several times

    I used to use the Julbo Colorado which look goofy, are uncomfortable, and fog up easily. These are way better, essentially a normal sunglasses frame with lenses dark enough for snow travel in the high mountains.

    Not much to it. Just works.

    Montebiancos are muy buenos

    • Familiarity: I've used it several times
    • Fit: True to size

    These are pretty solid for being on the economical side of glacier glasses. I've worn them for several weeks now and have not been disappointed. The frames may feel plastic, but lenses are quality. The instructions mention you shouldn't drive with them on because of the darkness, but I didn't think they were that dark. They really increase the contrast on snowy days. I don't bother taking the side shields on and off--I just leave them on all the time. I'd recommend them to anyone looking for an inexpensive pair.

    Great lenses

    • Familiarity: I've used it several times

    I used these on a Mt Shuksan mountaineering trip recently. They delivered what I was looking for, great eye protection. I had some fogging issues that were solvable by removing the side shields or just moving the glasses slightly. My only issue is that I wasn't able to ever quite get the fit just right, but each tweak made it a bit better. The fit issues I struggled with were a tendency to slip off my face and a bit of a hotspot above my right ear.I suspect these may work a bit better with a wider face. However, I couldn't have been happier with the sun protection and clarity.

    Block the Glare!

      They do a great job blocking glare and are just wonderful on the snow. They are a bit uncomfortable on the ears. The side shields pop off easily and it didn't take long until I lost one.

      Block the Glare!

      Best Sun coverage, u buy now!

        Just read Rob Wykoff's review, he's's foremost expert on sunglasses.

        These things fit so perfect they feel like they snap into my head and cover my eye from every angle from the sun (they are dark!)...

        ...and everyone that wears them at (6 people I know of) all say the same thing, u buy now!

        Good glasses

          I've had these glasses for over a year now and wear them when climbing in the WA Cascades. These glasses block sunlight and light reflection off of snow very effectively. My only complaint is that after several hours the arms of the glasses start to dig into my head just above the ears. So far its only been a minor annoyance.

          Awesome glass, but Rx beware!!!

            I got these glasses intending to add some prescription lenses to them. Mind you, I live in a rather urban area of northern Los Angeles, and finding a place that digitally cuts the lens was almost impossible. After I was able to find a place to do it, it was going to be over $500 not including the cost of the frames. There were extra costs added in for scratch resistance, polarization, and snow mirroring, but come! On to the glasses… They are awesome! They fit my large face really well, and are extremely light and comfortable. I recommend them to anyone with a medium sized face and above. My wife has a rather small face, and they fit her, they just look a little over the top big on her face. Julbo makes some awesome French made glasses, and their customer service is top notch. I called to order a strap for these glasses, and they sent it to me free of charge! That’s really rare these days.

            Please note that I wear these glasses for mountaineering, backpacking, and snowshoeing. I also have them on whenever I decide to wear my contacts. They fit great, are made extremely well, and look damn good!!!

            Julbo Montebianco - Highly Recommended

              Just got back from testing the Julbo Montebianco Sunglasses in the Sierras. With base camp set on Peaklet, we spent three days skiing and exploring the zones around Mt. Humphrey’s and Mt. Locke. Being sunny spring in the Sierras, my new Montebianco glasses with the Polarized Spectron 4 lens were put to the test straight away. From skinning and booting during the day to recouping at base camp in the afternoons, my new Julbos delivered exactly what I had hoped they would: unparallelled protection from the powerful spring sun, a comfortable and customizable fit (the arms are pliable allowing you to mold them for just the right fit), and crystal-clear optics. The removable side shields are great - on the longer/harder climbs, I popped them off and stashed them in my pocket to let my face breathe and to make sure perspiration did not get trapped inside. Highly recommended.

              Fear no Bright Light

                The sun is no match for these sunglasses! If you are on Snow or Water and need some serious sun protection these are great. They are Super Dark, not for evening driving or indoor use so if your buying these for late night clubin' they may not be for you. If you spend lots of time outside, get some!! you will love them!

                Does anyone have a problem with the lenses...

                Does anyone have a problem with the lenses fogging up? I've used mine a couple of time and they fog up as soon as I start moving.

                I had some similar issues. If I just moved them a little bit away from my face enough air entered to clear the fog up. If I was working really hard, removing the side shields did the trick.
