Castelli Undersaddle Mini Bag Black, One Size

You probably won't notice Castelli's Undersaddle Mini most of the time, but at some point, what you put inside of it will probably be the difference between you calling your spouse to come pick you up on the side of the road or just changing your tube and getting on with your ride. It's called the Mini Bag for a reason, so pack your ride essentials and leave the unnecessary stuff at home. Noticing the bag under your saddle wouldn't be such a bad thing either - it's made out of sleek, water-resistant material with Castelli's signature clean lines and classic style, and it's even sealed with a water-resistant zipper to keep your stuff safe during a shower. Reflective accents help keep you visible to motorists any time of the day, and the bag attaches cleanly and securely to your saddle with a hook-and-loop strap.
