The size of this phone is big and makes it difficult to find a good fitting armband. I have been using an armband I picked up at Walmart. The branding is Phillips, yes the same as the electronics maker, but I doubt Phillips actually makes the armband. I suspect they are just licensing out their name to be put on the armband. This particular armband is more of a stretchy spandex pocket that fits on your bicep. It does not have a clear plastic screen like most, but you can see the screen through the stretched fabric. The screen is also touch responsive through the spandex fabric. Because the armband is stretchy, it barely fits the Galaxy Nexus with a case on. At first I had to wear this armband with the phone up-side-down due to the location of the head phone jack, but I recently upgraded to Bluetooth headphones so I am back to wearing the phone right-side up.
I have also read good things about Tunbelt armbands. Model AB84 or AB85 will be the closest fit, but I don't have any personal experience Tunebelt.
