I have a women's big skinny wallet which I love love love!  So when my son asked for a wallet for Christmas, of course I got one for him.

Mine is red nylon and has a snap closure and change pocket which this one does not. This one is black leather, and thus more "classy" and suitable for my fashion-conscious son. Not having the change pocket is kind of a bummer though.

The leather one is a bit thicker than the nylon, but it's still much more compact than your average leather wallet.  This is because the inside is thin but durable nylon.  The best of both worlds, basically.

My nylon one has lasted several years with no issues.  I am assuming and hoping that this leather one is equally durable.
