This is a lot bigger than I was expecting, but that was my fault because if you pay attention to the picture and look at the passport you kind of see the size anyway, well, if you have a passport.
Is like a little "man's bag", and is not just for your passport. You got the front pocket covered by a flap, that would be an ideal place for the passport, actually, you may get three passports in there. The flap itself have a small pocket with a zip closing it, ideal for coins.
The main compartment have loads of space and it close with a zip too. Inside the main compartment there is another pocket, ideal for boarding passes folded up or something you don't want to get misplaced. This one closes with a zip too.
The material is of good quality and the zips feels and looks good too.
The only thing that lets it down a little is the strap, good for its purpose, but it could do with a little padding on it.
Mine is black, and it looks pretty cool too, it feels and it looks quality, hence the 5 stars.
