This year I went on an interrailing tour, just with my backpack. This is what you need:)
This deuter backpack is the best. It is relatively expansive, BUT it is super durable, the zipper works really goot, no matter how much you push into it. It has many different parts, so you can have your shoes, Phone, water bottle, toiletries etc. in...
