The quality of these is very good. They break the wind very well. Too well, actually. On my bike when going above 60 MPH they press hard enough on the clutch to be a problem. I'm sure I'll still use them but they won't be of any value on the interstate. It's possible to hold the clutch while using them but, for me at least, I don't have the strength to do it for my 45 minute commute. Unfortunately, the openings seem to fold up making it difficult to get gloved hands into them quickly, which is my reason for subtracting a star.
