SAG bags from Japan

I think the messenger backpack rules; I’m always on the lookout for cool designs. Here a bag by SAG (don’t forget umlaut) from Japan (which generally doesn’t use umlauts). This is the first I’ve seen in the states with my own eyes. After the jump, see how the bag reflects in the dark

The bag was spacious without being ridiculously big. I’m curious how waterproof it is with that long side zipper.
