I've always had a soft spot for backpacks. Now I have gone back to school, so I needed a backpack, where you can also accommodate even a Netbook, and especially a DIN A4 folder. At first I was skeptical when I held the Jack Wolfskin Perfect Day in hand. So small? But what! A space miracle! Large Folder, pens, Tüddelkram and 1, 2 books have loose space. For me more than enough. Workmanship is very good. When times projecting a thread, I melt the starting with a lighter and press it firmly. The front compartment has a few pockets for pens and small items. The large compartment has (unfortunately) no further subdivision or subjects. With the most important thing is the comfort. A Dream! If you're like me and so joined in the 80s, 90s, you know to appreciate the fact that the shoulder straps are wider at the shoulders and padded. Even worn loosely over one shoulder cut anything in the shoulder. Otherwise, the materials used are dibasic. Conclusion for me is that the Perfect Day is his money in any case worth. And thanks to the small dimensions and the chic look, it is also suitable for everyday use.
