As each and everyone of us handles wet and/or cold weather differently, it is hard to know what to recommend. personally I go for wearing 3 layers in bad weather, depending on the time of year, summer time it a light tee shirt then a cycling jersey and a light breathable waterproof jacket, Winter time I use a icebreaker Merino base layer, with either a cycling jersey and light breathable waterproof jacket, or a Cycling fleece depending on the temperature and it is raining, the nice thing about using light layers is you can quickly adapt to what ever the weather is.
