When shopping this item, it came up as Men's Hurley One and Only, and after marking or choosing size, it would come up as Young Men's.  This is the Men's Hurley One and Only hat; which incidentally was exactly what I was after.  I wanted the Icon style in size Small/Medium Flexfit, and it turned out to be the perfect size and exactly what I wanted.  I just waterproofed it today, and I've never owned a Hurley hat before, but I wanted something all white for summer to match some outfits I've bought recently (and some white on white Adidas hehe,) and so far everything about hat says quality, and the fit is as comfortable as I could possibly ask for.  If any of the stitching starts coming undone within the first couple weeks, I'll be back on here to update my review, but I don't think I'm going to have a problem at this point.  For right now, I'd recommend this hat to anyone interested.  Also; don't worry if it comes up as "Hurley Young Men's" in the description, as the sizes are for men.
