Nillkin makes a nice bumper case that i am currently using on mine. Doesn't add too much bulk, grip is good, and doesn't cover up the back so you can show off your Nexus logo. Also fits the pocket very well as compared to my previous bulky monstrosity. Using with intelliglass pro screen protector.
I agree, but your link doesn't have any protectors compatible for the N6 for some reason.
Here's an amazon link.
The great thing about this one is the black edges, you don't get the dreaded halo effect most glass protectors suffer from.
