Question about Dakine Split Roller

We have this bag. It has stood in the rain for a while and was watertight. But I can't say how long it is waterproof. I can highly recommend the bag. It's top quality and functional.

The zips don't seem to be made for the rain. It just depends on how long the part stands in the rain.

I don't think so, doesn't seem watertight to me.
