Top Glasses with good shelter and interchangeable lenses

The price - performance ratio in this Bille was unbeatable.
I had prepared these sunglasses that I had unfortunately lost :-(
After I tried a few others, I have come back again back on this model.
Sits just perfect and the eyes are well protected from the wind.
Was the main criterion for me. When motor paragliding glasses must fit comfortably and well protected against the wind.
Thanks to the interchangeable lenses can I use the glasses optimally.
