Will they last me a long time?

These should last you a while, unless your face gets run over by a truck while wearing them.

I have had mine for about 4 years as well and they are still in great condition. They made it through a trip to Europe and a lot of hiking and day tripping. Great pair of sunglasses.

my first pair of crosshairs lasted me four years (bought them in 2005) before they got knocked off my head and stepped on. Despite the thin frame they are incredibly durable.

Hey, Grant. If I'm looking for glasses to last me a while, I go for a more substantial frame. I guess it totally depends on your M.O. Are you hard on stuff? If you're hooked on these glasses, know that Oakleys always come in non-scratching cloth bags and zipper-sided hard cases. If you wrap them up in their protection every time you take them off, they'll last longer for sure. Good luck.----------Keep this in mind too bud. If you buy these from backcountry, they have a lifetime warranty on them. So if they break, you can send them back. So will they last you a long time? Thanks to backcountry's warranty, they'll last forever.
