This bag is absolutely perfect for a tablet 10.1 (so what comes with cover) and must certainly Letre for a portable 11.6 for which it is designed.
As too often you have the external dimensions (32.5 x 6.1 x 24.9 cm) while you are mostly interested in the inner dimensions so here they are 30.5 x 4.0 x 22.5 (measured by me -even) for info Case Logic recommends it for "Usable with following instruments: 30 x 2.3 x 21.1 cm."
The main compartment includes two large side pockets too small to hold A4 documents. The large side pocket has two small pockets and two pen slots and is large enough to accommodate the accessories (charger, cables, etc.) or even a mouse. The small pouch welcome your mobile and / or compact camera.
The protection seems more than sufficient in normal use (it is not a rigid hull) specifications, appearance is flattering, the zippers are of good quality, the finishes are perfect (neat seams). This bag exudes quality, which seems to be standard in Case Logic.
For less than 25 you will hardly find better in less than a big promotion.
