Just a note to let you know how well your seaspecs worked for me.
I just purchased a set of your sunglasses prior to teaching boating/PWC water safety course for Law enforcement at the Colorado River. I wore the seaspecs throughout the course and was very surprised by the comfort, clarity, and wind block while operating the PWCs at high speeds.
I have been working the River for about 15 years and have tried many high end and expensive sunglasses over the years. The seaspecs out performed the others in this environment.
