Mark Weisswrote a review of Julbo Vermont Spectron 4 Sunglasses on July 18, 2017
Familiarity: I've put it through the wringer
Fit: True to size
The very fact that they are flat gives a FUNCTION nobody has mentioned. You can put prescription sunglasses OVERTOP these glacier glasses and they (both pair) work perfectly fine together. Glacier glasses that curve around do not allow other glasses -- let alone prescription -- atop the glacier. For driving, glacier isn't enough filtration with car butts & windows beaming sun at you. So presecription SUNglasses ATOP these glacier glasses is the ticket. For style only -- yes they're cool. I've gotten intrigued comments. But please do REALIZE the EASE of doubling-up -- which other glacier glasses would not allow you to do.
