Castelli is a Team INEOS sponsor and development partner and the clever design team not only creates finely crafter race garments and accessories, but also the gear bags the team utilizes. With the Pro Race Rain Bag, Castelli has created a vertically oriented modular gear bag system with a main compartment, as well as a zip-off grab bag compartment, and a shoe bag that clips on for security, but keeps ripe and/or wet shoes isolated from the rest of your race gear. Internal mesh organizers in the main compartment keep items secure. Due to the lightweight and compact form of cycling gear, the Pro Race Bag can carry plenty of gear despite it's compact form and 51-60L listed capacity. A Castelli feature most of their bags includes is a red internal liner that makes visual identification of stored items easier and quicker.

As a waterproof bag, this set-up features a durable and repellent exterior material that is similar to a softshell membrane system that keeps water out but does breathe a little to reduce potential moisture build up inside. Large, damage reducing zippers are unlikely to catch on your gear, are easy to use, and waterproof. Castelli has created a series of labeled pockets/compartments that make organized storage a breeze, though they are quite bold visually. Remember, this bag was created to make gear management more practical, including knowing exactly where everything is without emptying the bag out. The usual Castelli attention to detail is here, including the zippers, zipper pulls, durable padded top carry handle, and overall construction quality. It may not be the bag for everybody, but if you recognize and embrace its features, the Pro Race Rain Bag may well be the best option for race bag no matter the weather.
