I drive more recently by bike to work and wanted to be a viable alternative to traditional laptop bag. For the price, the backpack makes a very good impression, my 17inch laptop fit in and also the change of clothes and the associated stuff. You can bring outside drinks bottles and the small compartments are well divided. The backpack itself is pleasantly light and cushions the laptop perform well. Insgasamt I can yet say nothing negative, which I'm not yet driven in the rain. For me as a woman, it is rare that such backpacks fit well also in the shoulder area. I would recommend him.
