I bought this case to replace my wife's Oakley case for her Oakley Darts.  The case is pretty much a perfect fit.  It is just a slight bit bigger than the Oakley hard case which is perfect because the glasses fit without having to fuss to get them in the exact placement like in the Oakley case.  It has the soft felt inside so it will not scratch your glasses.  I'm ordering a couple of more for some of our other glasses!
