Silca Mattone Ultimate Seat Bag

The SILCA Mattone Ultimate Seat Pack is a compact under-saddle storage solution designed for road riders and performance-focused cyclists who want essential carry capacity without sacrificing a clean, low-profile silhouette. Constructed from laminated TPU composite fabric with RF welded exterior panels, the Mattone Ultimate replaces traditional stitched seams with a smoother, more weather-resistant shell that sits tighter under the saddle than conventional seat packs. A clamshell clamshell opening reveals a single main compartment paired with a flat lid pocket, keeping flat kit essentials like a tube, tire lever, inflator, and multi-tool organized and accessible. The BOA Li2 closure system uses a low-profile aluminum dial with a TX4 soft lace cable for precise, secure adjustment without bulk. A Hypalon reinforced mounting strap with an integrated attachment point for a light or camera rounds out the mounting system.
