Silca Mattone Ultimate Seat Pack

The SILCA Mattone Ultimate offers minimalist on-bike storage in a compact, performance-forward seat pack. Engineered specifically for road riders and racers who prioritize a low-profile setup, this pack forgoes traditional stitched canvas construction in favor of RF-welded exterior panels and TPU composite fabric. Its seamless design creates a smooth exterior that mounts closer to the saddle rails while limiting water entry points.

Due to its material composition, construction, and compact size, the Mattone Ultimate weighs a featherweight 44 grams (1.55 oz), a 50% reduction compared to the 90-gram original Mattone. Inside, the 0.4L clamshell opening reveals a simplified single main compartment and a flat lid pocket.

Securing the pack is the premium BOA® Li2 closure system, which is an upgrade over the original Mattone’s standard dial and open guide loop to a low-profile metal dial with a soft TX4 lace cable. This system provides precise, micro-adjustable compression that tightens around the minimalist pack's TPU body, pulling the entire footprint upward to eliminate bag sway. Additionally, its Hypalon-reinforced strap and water-resistant YKK zipper keep everything secure and dry in harsh weather.

Complete with an integrated mounting strap for a light or camera, the Mattone Ultimate is the choice for weight-conscious cyclists seeking utility with less bulk.
