These button-fly 501's are EXACTLY the same ones I wore through my highschool years in the mid-80's, I went to dress slacks after Grad. to getting/working hotel audit jobs to get me through collage (study good 2-3 hours in middle of night)--now for about 10+ years years I've tried EVERY kind of store to get a couple pairs of those wonderful button-fly 501's (I dislike zippers)-and for 10+ years could not find them, until NOW..!!!! put me into a members-only blue jacket and white hightop reboks and I'd be be back in 10th grade..haha
THESE ARE THE REAL THING-NO ZIPPER-LEVI's

Where the bad reveiws come from..(I almost didn't buy these due to them!!!), I can only think from --Rivival Stores, or plain lies, or some "amazon" mix-up, I honestly don't know.
What I DO KNOW= I'm over-joyed to FINALLY have two pairs of Genuine Button-Fly 501's, after 10+ years, I wish I had ordered 4-5 pairs !!!!

The "Bad" reveiws - may have merit, as one "store"-differnt topic, said something about -AMAZON- just put their their name on a a batch on items that they didn't sell (shrug). its a Mystery.
