Product review (4 stars): Great protection, look great, ride up a little...
Excellent glasses. Got them for all my field and shop guys for protection from the sun and against eye damage. The video on these showing comparison to regular sunglasses during impact testing was powerful. Needed something that looked good (The better they look the less I have to remind my guys to wear them) that actually provided protection.
Only 4 stars because they squeeze the sides of your head and when you squint or smile they lift off the bridge of your nose. Traditional glasses that loop around the back of your eyes tend to "ride up" less. Maybe just an issue for my chubby head, great glasses though.
