Rugged case with built in magnet?

[tacopox]

Are there any rugged cases with a built in magnet? Similar to the rock case, http://www.rokform.com/iphone-6-case/?

I don't need the mount opening that comes on the rock case and I'd prefer a rugged case with a built in magnet without that opening.

Im pretty sure there are two different backs on that case.
One with the opening and one without.

Both are magnetic. So if you dont want the opening just use the one without it.

Im about to order one of these cases too but the aluminum one.
