Cotton becomes nasty when wet, but if you can switch it as necessary you can get away with it. Prepare to switch out any moisture carrying garments - socks, insulation garments, hat, gloves, possibly even shoes. People back in the day had several pairs of boots to dry them out alternately.
Get a waterproof breathable raincoat, goretex or similar. ALSO get a non-waterproof jacket against the wind, abrasion, dirt etc. Only wear the raincoat when it's actually raining. If the raincoat is reasonably long, you can get away with not wearing waterproof pants sometimes.
Generally beware of what hikers suggest (like most on this board). They are less hard on their gear and cannot easily switch it (weight becomes prohibitive). If you work from a room or car with storage you can do that.
