Are there any sleeves which offer good level of protection?

Hi,

I just got my first ereader (PocketBook Touch HD 2), and I am looking for the appropriate protection when on the go. However, I dislike case/book-type covers as I prefer to hold the reader without a case.

Are there any sleeve-type covers for 6" readers which offer the (drop and bend) protection similar to book-type covers? I have found some which seem to be ok in that regard (PU leather + some sort of rigid inserts, see here) and I was wondering if anyone can recommend some?

There are quite a lot of soft sleeve covers, but those probably just provide scratch protection...

Thanks :)
