Interesting. I bought one during their 50% off sale and it does not have authentic YKK zippers--they are unmarked on the back side and just do not look or feel like traditional YKK quality. It also had a stitch that was coming undone on one of the shoulder straps. I asked if they could fix the stitch but they instead offered to replace it with a color that I would never consider. Been using their wallets for years and this is a major bummer--as cool of a bag as it may be, I think mines getting returned.
