Out of all the other brand names such as Wiley X, Revision, etc, ESS CDI Sunglasses is all about quality. This pair is not to big and not to small. Its a medium fit which fits me perfectly. I use them as everyday sunglasses. If I need the clear ones for the shooting range, I just swap the lenses out with no problems. I also use these for backup glasses since you can get clear lenses with prescriptions. If you are ever going to buy any pair of sunglasses get it from OpticsPlanet. They have the best prices all the time.
Pros: Easy to change lenses and great for prescription lenses.
Cons: It could use a better neck strap.
