prada wallet for men....please help me!

  1. So, like I said in my introduction, I am looking at some Prada wallets that really caught my attention the other day. Beautiful ones, ok ones, ugly ones...Ive been through them all. However, one really caught my attention as it is what I want and need sort of. The Prada M510 nylon. However, on one website styledrops they said that its for men and big enough for me to carry on my back pocket (woopeeee!!), but on another website (dont remember) the same exact wallet was placed under womens wallets and the dimensions were alot bigger, as to be kept inside a bag and/or purse. Does anybody know of this particular wallet, if its indeed for men or women, and how big exactly it is??? All help would be greatly appreciated.
    thnks alot,
