Touch Good protective cover

Hi everyone!
Since the Kobo Touch it's a mobile device...well, I would like to carry it around :)
I'm looking for a good protective cover, and I would like to have some hints about the cover that you are using.

What is a "good protective cover" for me:
- book-like cover like this, not a sleeve/case like this;
- tough front cover (the reader could be randomly put in my trekking backpack...) to avoid screen damage (also: what about the chance of display damage?)
- all buttons and connectors must be reachable with the cover on
- well fitted for the Kobo Touch dimensions
- leather and similar worries me a little (prone to wear and tear). Share your experience about this

Thanks to everyone!!!
