As long as they still work (no bad tears, zippers and all still work) why worry? Do you really think the deer are gonna look at you and say " dude your camo is faded?" I have BDU's that I have worn for 10 years or more, yeah they are faded and I even have to stitch them up from time to time, but they still work.

I wouldn't worry about it, with the ever changing seasons you will never get a camo to blend perfect, new or otherwise so whats the difference?Just use them till they completely wear out then buy new.
