Ride light and stay prepared with one of the most weight-conscious saddle packs on the market. The SILCA Mattone Ultimate is a minimalist, weatherproof seat pack built for road riders and racers who want essential on-bike storage without any added bulk or sway.

At the heart of the Mattone Ultimate is SILCA's RF-welded TPU composite construction. Instead of traditional stitched canvas panels, the exterior is seamlessly welded, creating a smooth, low-profile shell that sits close to the saddle rails and limits points where water can get in. Combined with its compact 0.4L capacity, this construction lets the pack weigh just 44g — a 50% reduction over the original Mattone.

Closure is handled by the premium BOA® Li2 system, a low-profile metal dial paired with a soft TX4 lace cable. It delivers precise, micro-adjustable compression that cinches the pack upward against the saddle rails, eliminating the sway that plagues bulkier bags. A Hypalon-reinforced strap and water-resistant YKK zipper round out the weatherproofing, keeping your essentials dry no matter the conditions.
