The SIlca Mattone Saddle Pack is a water-resistant, ultra-compact seat bag that attaches to the rails using the BOA® Closure System. It features a unique zipper design allowing it to be accessed while on the bike, or to open like a book when removed from the bike for easy access. This saddle bag is ideal for cyclists who are looking to carry a spare tube, CO2, Multi-Tool, and some cash in a discrete, water-resistant package. The Internal divider holds ID, credit card or cash while also protecting your tube from your multi-tool!
