I mostly use 2 coats, in the summer and spring I use a denim jacket (I live in a warm country so it's mostly for the night or if it's windy that day). In autumn and winter I use anorak (most of the days is not that cold but I'm a cold person). So it really depends on your climate but I mostly would recommend this types of coats for this climates.

For anoraks, I didn't try it but the people that did recommend Patagonia. Is one of today's brands more longer lasting, and one of these few brands that really care about the workers and the planet. You could also find some items in 2nd hand stores.
