Well, I am living in Germany, what is perhaps a few degrees warmer in the summer, but even in Winter I recommend:
FOR HIKING A JACKET HAS TO HAVE A FULL LENGTH ZIPPER !!!
ANORAKS ARE CONSTRUCTED BY AND MADE FOR INUITS !!!
For hiking the best layering is the following:
Summer:
T-Shirt
Shirt with buttons, pouches (classic)
Fleece Jacket
Light rain proof.
The Shirt has to be so large, that you can wear it over the Fleece Jacket as Windstopper and spark protection
Autom and Spring till 0*C:
T-Shirt
Shirt
Fleece Jacket
Heavy cotton shirt or light BDU Jacket
(Waterproof if needed.)
Winter:
Additional a thin pullover under the Fleece Jacket.
As you see, with that system you can play around to find the optimal combination of the day.
Parts of it can be washed and dried if it isn't to cold.
