Overview

How Does the Silca Mattone Ultimate Compare to the Original?

The Silca Mattone Ultimate Seat Pack is the lightest saddle bag Silca has built, at 44 grams against 90 for the original Mattone. It gets there by dropping stitched canvas for RF-welded TPU composite panels, which makes the shell seamless, leaves water fewer places to get in, and lets the bag sit closer to the saddle rails. Capacity is 0.4L, enough for a tube, a CO2 cartridge and regulator, tire levers, and a multitool. Dimensions are 128 x 60 x 91 mm.

Closure is the BOA Li2 system, a low profile metal dial running a soft TX4 lace cable. It gives micro-adjustable compression that pulls the pack up against the rails rather than only cinching it shut, which is what kills the sway and the rattle. A Hypalon reinforced strap and a water-resistant YKK zipper handle the weather, and an integrated mounting strap on the outside takes a light or a camera. Inside, the clamshell opens to one main compartment and a flat lid pocket. We stock the Standard and the Grande at the Lab, so you can put all three side by side before you spend up.

How is the Silca Mattone Ultimate different from the original Mattone?

The Silca Mattone Ultimate weighs 44 grams against 90 grams for the original Mattone, and holds 0.4L instead of 0.5L. It swaps stitched canvas for RF-welded TPU composite panels and upgrades the closure from the standard BOA dial and open guide loop to the BOA Li2 metal dial with a TX4 lace cable.

What fits inside the Silca Mattone Ultimate Seat Pack?

The 0.4L main compartment of the Silca Mattone Ultimate holds a tube, a CO2 cartridge and regulator, tire levers, and a multitool. There is also a flat lid pocket for smaller items, and an integrated mounting strap on the outside for a light or a camera.

Does the Silca Mattone Ultimate Seat Pack sway or rattle?

The BOA Li2 dial on the Silca Mattone Ultimate applies micro-adjustable compression that pulls the pack upward against the saddle rails rather than only cinching a strap shut. Silca designed it that way to eliminate sway, and the welded TPU shell has no stitched panels to work loose.

Is the Silca Mattone Ultimate waterproof?

Silca describes the Mattone Ultimate as weatherproof rather than waterproof. The RF-welded seamless exterior limits the points where water can get in and the YKK zipper is water-resistant, so it is built to shed rain rather than to be submerged.
