Not a changing bag, but big enough for snacks, waterproofs, change of clothes, colouring book etc.
I have a Roka Canfield B medium (15l) at the moment and it is perfect until it rains and everything gets soggy. So looking for something similar but waterproof!
Brightly coloured is a bonus as I'd like it to be noticeably different to my boring black work rucksack.
Any recommendations?
