I received my PE sleeve on Friday.

It's custom made for the PE, with the logo and name emblazoned on the side and spine, respectively.

The outside is microsuede (I believe that's the term) and the inside is faux fur. On one side is a small pocket (for putting the AC adapter, or better yet a Mifi device). On the other side is a wide band through which you can slide your hand (flat against the PE) in order to carry it more comfortably (i.e., rather than grasping it with your fingers).

If worthwhile accessory to get if you take your PE out of the house
