Bumper Case for Galaxy Nexus (or other phones)

This works with many phones, not just the Galaxy Nexus.

This will protect the sides and corners of your phone, but not the back. If the back gets scratched up, you can get a new battery cover for a couple bucks. 

Most of the protection with less of the bulk.
