Sorry to chuck this in but I really find rain jackets don't work- no matter how big the pit zips or how breathable the fabric you in the end become wet from the sweat.

Instead DH and I dress for the chill and cold. We layer wool (which stays warm when wet) with warm, windproof jackets of heavy material. Yes we end up wet but we are not chilled. We also find that waterproof socks (Seal Skins) with waterproof overbooties are great also as it also is the water in your shoes that chills you down as well as being really annoying.

We also always took a change of clothes to our cycle club to change into as soon as we got off the bike so we NEVER wore wet clothing home in the car.

And when we rode in tropical rainstorms, we didn't even bother with wet weather gear, we just got wet. It was warm enough we didn't get chilled. Water gets in everywhere and you would probably have to wear rainpants, layered over booties and a huge jacket/poncho with a full hood to stay dry.
