The Road Runner Bags California Burrito is simply designed in a way that’s effective, elegant, and durable all at once. This 3.3-liter, tube-shaped bag (about the size of a six-pack) fits all the essentials you might need for a day on your bike: wallet, phone, keys, some tools, snacks, and a light jacket. This is the biggest bag that Road Runner makes—yes, you could get away with a smaller bag, but having some extra room is convenient. The nylon straps are movable to fit your bar width, and that simple yet unique feature makes this bag stand out from the other bags we tested. It has a single zipper that’s easy to operate while you’re on your bike and side pockets for small items you might want to access quickly. Made of durable Cordura nylon, it comes in six fun colors to match your bike. The California Burrito also readily converts into a shoulder bag with Road Runner’s universal shoulder strap (sold separately).
