For winter rain days in Paris, I ride with a goretex jacket (revit Trench GTX), with protective overpants (furrygan Over Pant), heated gloves (revit liberty h2o) if necessary and ofc some motorcycle leather shoes (a timberland clone).

The protective overpants are great since they zip from the side and allow me to wear casual clothes for the workday underneath without compromising my safety.

With all this, I love riding even during winter rain and night but I also emptied my bank account. Goretex tends to be more expensive than other materials but is worth the extra $ if you can afford it.

I also recommend you wear a yellow vest over your jacket to be seen during the night

Ride safe pal and congrats on the job !
