Amazing!  Vertical card storage holds full length cards while larger billfolds are usually too tight a fit for cards.  Fits pants pockets easily with less bulge than large billfolds, yet carries everything I usually carry.  While this may seem unlikely, it is true and I will keep buying this size wallet from now on.  Has zippered pocket that can be used as a single pocket or as two separate pockets--one on each side.  Plus, it has 4 internal pockets and 8 exterior pockets--2 per panel or 4 per side (front and back).  Have used for nearly half a year and does not show any wear.
