Well-known in design circles and on blogs for its folded polypropylene backpack and unusual iPad cover, Solid Gray looks to fill the gap in the mobile boom box market with its speaker-outfitted backpack, dubbed the Basspack. Currently just a working prototype, the collaboration with Case of Bass adds boombastic sound to the geometric backpack design. No word yet on availability or audio specs, but the very idea of it makes designophile music fans giddy, but their neighbors? Perhaps not so much.

Eindhoven studio Lijmbach, Leeuw & Vormgeving rocked our world with the future-forward Solid Gray backpack. Naturally, they've followed up with a minimalist-friendly iPad tablet cover. 

Incredibly, the cover is made from one sheet of material, cleverly folded into a shock-protecting beautiful object. It's made to take on the subway or from room to room and (as seen in this video) folds out into a sleek and ergonomic workstation. All the better to make the other entrepreneurs at your co-working space drool like baboons.

Solid Gray has tablet covers for iPads 2, 3 and 4. All available via solid-gray.com.
