This is real leather but the quality is not very high and its thin leather but the bag is very sturdy and I do like it a lot.  This is the bag I wear for errands and is large enough for a wallet, small bottle (and I mean small like less than 16 oz) of water, and a few other things.  Its not big or roomy at all.  The straps are really long but I like the zipper down the middle so you can wear the bag as a sling or backpack.  Most of the time I wear it as a sling because the straps are kinda long and the bag is small it swings on your back when you wear it as a backpack if there isn't enough weight in the bag to keep it stationary.
