The list does look a bit incomplete.
But regarding the clothes ... never bring jeans on a tour. Why? They are bulky and take way too long to dry. Everything you bring should be lightweight and quick drying. When you go shopping, before you try things on, roll them up as small as possible. If the result is something still quite large and bulky, put it back and try something else.
And as I mentioned in another thread, aim for 2 purposes for each item. Wicking T-shirts instead of jerseys. Long-sleeve merino top instead of a long-sleeve jersey. Etc.
