The bag is gorgeous, surpassed all expectations! I tried the glass, tried the mesh, I liked the empty window more. Adult border terrier 12 kg fit perfectly, with stock (this is our third bag, in 10 years, so I know what I'm talking about). The quality is very good. Well thought out. Of the minuses-long delivery by DPD to the door (5 days to Russia and a month in the country). Also, the backpack came with dents, but the seller quickly settled the claim. Keep in mind that the backpack is covered with a protective film, this is not a finish, it needs to be removed.
