For MBA 13: optimal

For my new Macbook Air 13 "I look hard for a suitable sleeve, so it does not verkratz on the way to the university and to work.
Prerequisite to the sleeve should be an opening at the narrow end, so that I can leave the Sleeve in the backpack and the MBA has just pull it out.

The be.ez LA robe pocket for my needs just right! The MBA fits perfectly pure (just not as a room like this
whole MBA / MBP-pockets) and it also looks very stable.

The only disadvantage of the case is in my opinion, their stiffness. The Sleeve is totally stiff! Perhaps this sets the time.
(Although this is not really a nuisance, just bothers me that something as all my other Sleeves are cuddly soft)
