What to take to the Camino is always a good question that will be determined by personal lifestyle and also by weather and gear that you have.
I strongly recommend you have the most technical and ultralight gear, but of course they are expensive. The more you get lightweight material the more expensive it gets.
In this Camino i had the probability of light rain. So i choose not to take heavy waterproof clothes. I only took a kind of “poncho” with 2000mm of water column resistance. Not much but it would do for light and occasional rain.
