"'HI' is just such a banal word, almost meaningless, so I thought it would be fun to treat it ironically and make it exuberant," says Threadless designer Ray Fenwick.

Take a super-slim case from Griffin, add original art from Threadless.com and you get HI, the latest Griffin + Threadless design. HI snaps around your iPhone to provide protection from scratches, dust, and boringness, adding less than 1mm of thickness to your iPhone without blocking the dock connector, controls, or headphone jack.

But don’t dilly-dally. Like the shirt designs they share, we’re building these cases in limited quantities. With this much awesomeness crammed into one thin case, we expect them to sell out quickly. When they’re gone, they’re gone. So hop to it. Click. Buy. Be happy.
