I'll be touring in Denmark in a few weeks, where there is the possibility of serious rain and wind (though I hope not). Last year, riding in France, I ended up doing 60km in a driving rain wearing shorts and a pretty big (non-cycling) goretex jacket. The goretex held up pretty well, but it was hot and it grabbed the wind. My shorts were soaked, which was okay. My shoes were too, which was not okay.
To prepare better for rain-soaked days, I am thinking of getting a real cycling rain jacket and some kind of overshoe. I've read very good things about the Showers Pass Elite jacket. It sounds perfect, but it's pricey. Showers Pass has a much cheaper jacket, the Club. They also sell waterproof overshoes.
We'll be riding about 50-60 miles a day.
Has anyone had experience with the various Showers Pass jackets/overshoes, or have other recommendations?
