01Cold rain: waterproof everything
When it is cold and rain is likely, you want a proper waterproof jacket, waterproof winter gloves and waterproof overshoes. Keeping your hands and feet dry matters most: once they are wet and cold, they stay that way for the rest of the ride.
Mudguards (fenders) do as much for your comfort as any piece of clothing: they keep the spray off your back and feet, and your riding partners will thank you.
02Mild rain: a packable jacket
In the mild range, a packable rain jacket is enough. It is lighter and breathes better than a winter rain jacket, and fits in a jersey pocket when the rain stops. Thin rain overshoes keep your shoes and socks dry.
03Warm rain: optional
When it is warm, many riders skip the jacket entirely and accept getting wet: you warm up quickly and a wet summer jersey dries fast. Take a packable jacket in your pocket anyway for descents or if the temperature drops.
04Chance of showers
When the forecast gives a moderate chance of rain (40–59%), kitcheck.cc lists a packable rain jacket as optional. From a 60% chance, it treats rain as likely and adds the full rain kit for the temperature. With a GPX route, the calculator also tells you if the rain arrives or stops during your ride.
