I purchased these glasses to use the multiple lens "interlock" system. The problem is that once the lenses are changed there is a "gap" between the frame and lens letting light in.
Nice lightweight soft shell. Love the front pockets for easy access with lots of room. Does a great job blocking the wind and is very breathable.
Second pair of G3s. These binding are solid without any problems. Wouldn't take anything else into the backcountry.
