Amazing dark lenses
These lenses are perfection. If you want the darkest lenses you can find for insanely bright sunny days, get these. Plus the frames are so lightweight. They are easy to wear, fashionable (I took off the side pieces...) and I love them.

Antarctica 🇦🇶 specials
These are my second pair of Julbos. I like the look and the build quality of these glasses. I also love the removable shields so I can wear them casually. I am headed to Antarctica in mid-August and will be there through the polar summer with 24 hour sun and lots of white snow and ice for it to reflect from. I am counting on these glasses to get the job done in that environment. -Ashley N.
