I comes with a waterproof case. Without the case it says it's "weather resistant" which I interpret to be just from normal water from landing in the snow or riding in light rain.
Yea I have it with the case. I also have the ROAM which is clearly spec'd as saying water proof to 1 meter. I have the water proof case for my roam as well for snorkling etc. The +2 does seem to say its resistant to water up to 1 meter.
