Bought for a 14 inch notebook. Star sky motif. I rate the shell as a lightweight protective sleeve against scratches and dust, not as protection against impact and fall. The sleeve is made of neoprene with an outer fabric layer. It is soft, reasonably grippy. The zipper is good. The bag fits well, the dimensions given are complied with. The shell initially smells strongly of chemicals, they should necessarily unpack and ventilate one week. Even after that there remains a slight odor. Who is odor-sensitive, which should better not buy the bag.
