I was looking for a sleeve for my Lenovo Yoga 13 and I have two versions of purchases for security: "Macbook Pro 13.3" "and" Macbook Pro 13.3 "(late 2013)". The latter is the version with additional pockets.
Theoretically, the Yoga fits in both sleeves, however, is "late 2013" version a bit too narrow and the notebook by only quite difficult to pull back ... clear for me too hard (so tightly a bag should then not be yet) , That will certainly also with the very grippy surface of yoga together (in combination with the surface of the felt of the sleeve). Both sleeves have the same width, but the side seams at the simple seem "late 2013" version to have been a ticking set narrower, whereby the interior then becomes a little narrower.
In this respect clearly applies my "recommendation" of "Macbook Pro 13.3" "- version (NOT" late 2013, "without pockets) Here the Lenovo is secure but can be pulled out all right..
I hope I could the Lenovo Yoga 13 owners to help a little ... :)
