The Castelli Pro Race Rain bag was designed for and by the best in order to handle any sort of weather. This packable bag is 100% waterproof, and perfect for storing a 3-week long tour's worth of kit and riding gear. We're fans of the separate shoe pocket as it keeps our smelly shoes separated from tomorrow's clean kit. The main compartment has spots for other bits of kit, so we can separate our kits the night before in prep for today's big event.
