Outstanding - Wiley X PT-1 Interchangables Sunglasses w/ Interchangeable lenses

I used these sunglasses in OIF 1, OIF 3, and now in OIF 5. I have changed the lenses thousanda of times. They are still holding good. I have used them for 22 months in Iraq and I am just now ordering a new set of lenses. The only problem is the rubber piece that hugs your head, it falls off all the time now.
Pros: Ease of use
Cons: too many components
