Searching for Everyday backpack

I have two small deuter backpacks for several years now. Both are dying right now and i need a New one. Best would be Kind of BIFL.

I use them everday for Shopping, holiday or general Transport by foot, bike, train or car.. so i am searching for a real Allrounder. Small enough as daily driver but with enough space and a Bottle holder on the outside. And rainproof.

My current backpacks... the Straps are not Straps anymore, the raininsolation is crumbeling and so on. Any Suggestion? For EU Market.
