What is the SILCA Mattone Seat Pack built for?

The SILCA Mattone Seat Pack is the original version of SILCA's brick-shaped saddle bag, built around the BOA Closure System that makes the whole Mattone lineup stand apart. The BOA ratchet delivers more than 15 times the holding force of Velcro, uses a high-friction Hypalon strap for secondary retention, and physically cannot loosen under vibration or impact. You set it once and forget it. No adjusting mid-ride, no swinging, no rattling against the seatpost on descents.

Compact and weather-resistant at 0.5L, it holds everything for a roadside flat fix: a tube, two CO2 cartridges, a regulator, tire levers, and a multitool. An off-center YKK waterproof zipper lets the case open flat like a book off the bike while still giving quick access on the bike. For longer rides where two or three tubes makes more sense, step up to the Mattone Grande. For everyday training, club rides, and races where you need the basics and nothing more, the Standard is the clean, right-sized choice.
