Trying to find a medium-ish size handlebar bag with a pocket on top for a large smartphone (i.e. Galaxy S3). The sort of pocket that's clear and you can still see and use the phone. Prefer rain-proof.

I can find cell phone cases with a very small storage space under it but handlebar bags with a smartphone pocket on top seem to be rare or nonexistant. Maybe I'm just looking in the wrong places.

Thanks!
