SILCA's most premium seat pack yet, the Mattone Ultimate features BOA® Li2 closure system, weatherproof RF-welded construction, and weighs just 44 grams.
Indianapolis, IN / Amsterdam, NL – August 4, 2026, 11:00am EDT / 17:00 CEST – SILCA, leader in marginal gains, and known for its dedication to precision and quality in cycling products, today announced the launch of its 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). That’s a 50% reduction compared to the 90-gram original Mattone. Inside, the clamshell opening reveals a simplified 0.4L single main compartment and a flat lid pocket.
Securing the pack is the premium BOA® Li2 closure system. An upgrade over the original Mattone’s standard dial and open guide loop, the low-profile metal dial and soft TX4 lace cable make operation smooth and precise. This system provides micro-adjustable compression that tightens around the minimalist pack's TPU body, pulling the entire pack upward to eliminate 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 premium utility with less bulk.
