I can't speak for RFID blocking, but this little wallet packs a punch. I've been using it for a couple of years now and the edges are showing signs of wear right now. I use it as a handbag with a front pocket, so it flexes a little when I'm sitting, but I mostly slide it into my pants pocket's position.
