In light rain it's fine. In stormy weather, it puts up a valiant effort that is ultimately compromised by the fact that it has a zipper.
One nice thing about the case vs. a rigid handlebar bag, though, is that since you don't need a rigid base, water tends to flow out of it a little faster. One thing I found with the Arkel handlebar bag last year during a 400k that had 20+ hours of rain was that there was basically a small lake at the bottom of the bag because it wasn't draining away.
Regardless, everything that I have that is remotely vulnerable to moisture goes into a ziploc bag.
