SeV launched the Transformer Jacket that switches from jacket to vest via magnets:

“The Transformer Jacket’s 12 powerful rare-earth magnets allow you to transform from jacket to vest in the blink of an eye…and back again just as easily. We call it our TEC-MAGTM system, and it’s unlike anything you’ve seen before. With 20 pockets (the iPad fits in all sizes) and clear-touch fabric for easy cell phone use, this jacket has everything you expect from SeV with the addition of this one revolutionary feature. It’s reminiscent of the magnetic iPad smart cover, as one early reviewer pointed out.“
