Silca Mattone Seat Pack

Unlike traditional velcro straps that can loosen over time, the BOA dial provides a ratcheting, mechanical closure. This ensures the bag stays cinched tight against your saddle rails, completely eliminating the swaying and rattling common with other seat packs.

Yes, the 0.5-liter capacity is specifically designed to hold a standard road tube, a multi-tool, and a CO2 cartridge. The internal pocket helps keep these items organized so they don't rub against each other while you ride.

The bag features a high-quality waterproof zipper designed to keep your repair essentials dry during wet rides. While it provides excellent protection against road spray and rain, it is not intended to be submerged in water.

The Mattone opens completely flat, which is one of its best features. You can lay it out on the ground or hold it open to see exactly what you need without having to dig blindly or risk spilling your gear.

Because the Mattone uses a strap-on mounting system that attaches to the saddle rails, it is generally compatible with most dropper posts. However, you should ensure there is enough clearance between your saddle and the tire when the post is fully compressed.
