You can shoulder anything with it. The backpack of Bayer 04 is not only rainproof, but also offers you plenty of storage space for everything you need on the go. The large inner compartment, which can be enlarged with the practical roll top, has another inner compartment with a zip. There is also a side pocket, a carabiner and two pockets for a mobile phone or powerbank. The back is padded and also offers you a secure inner compartment with zip. On the front, of course, you will find the beloved Bayer 04 logo on another zipped compartment.
