Bought at the last moment for a 26 mile walk. Used with a two litre hydration bladder I already had. The vest was super comfortable and held bits and pieces very neatly - I used one of the water bottle pockets for my iPhone, and the other one for a Decathlon 250ml bottle. The only caveat was that I carefully put my car keys in a zipped pocket without realising there was another, open, zip at the other end. Fortunately the keys stayed in! There are so many pockets and I think I’d only end up using about half of them.
