Have this bag for a Lenovo X1 Carbon Ultrabook ordered. The fits of width purely perfect. In the height is still ~ 5cm air. The bag is sufficiently padded. Not really wears on. In the side pocket of the PSU, ne smaller mouse and a couple of mini Displayport adapter fit purely. This is but only if you pack carefully :-) The workmanship is good. The initial typical plastic odor dissipates quickly and is probably to describe compared to other plastic items as "discreetly". The bag is with me for several months in daily use. I wanted a compact bag with a discreet appearance and good workmanship - I'm happy. If you want to pack more like the parts described should take up another bag.
