PowerSupport made two versions of the AirJacket for the iPod touch - one with a loop hole, and one without. I have the one without, so it's perfect for the 6.
I am using the Ulak Hybrid ( from Walmart also on Amazon) and it fits perfectly- I am using the Iflash tempered glass screen protector as well within it. I found that the case fits fine, but some of them are now being marketed as both 5g and 6g
