Ideal bag - unfortunately too small

First, the positives: construction and design of the bag I find ideal. Good gepolterst, two large side pockets (for cable, AC adapter, media ...), with carrying handles, which can be hidden - and still slim and compact.

Unfortunately, the bag is too small for "normal" 15.6 inch laptops. I wanted to wrap up the Lenovo G500s in it, but the stuff was so much tension that the zipper no longer allowed to pull. The sheath is more suitable for 15-inch equipment or very slim Ultrabooks.
