This wallet is a little large to fit in a pant pocket.  I like that the inside pockets on each side are large enough to fit bills in.  I did not feel comfortable storing money in the large pocket with the opening at the top, but this was perfect to store my boarding passes.  I don't have any input on the RFID blocking feature, since I have no way to test it.  It is nice quality and should last a very long time.
