Description

Clean, Low-Profile Bag For The Essentials

The Silca Mattone Ultimate refines Silca's seat pack design by reducing excess construction and simplifying form. RF welded exterior panels replace traditional stitched construction, creating a smoother exterior that sits closer to the saddle while limiting water entry points. A clamshell opening with a single main compartment and flat lid pocket keeps tools easy to access, while the BOA® Li2 closure system ensures secure retention beneath the saddle.

Features:

  • TPU Composite Fabric: Laminated technical fabric designed for RF welding, providing a smooth exterior surface with high durability and resistance to the elements.
  • RF Welded Construction: Panels are RF welded rather than stitched, eliminating needle holes and reducing seam exposure for a more compact, weather resistant structure.
  • BOA Li2 Closure System: Low profile aluminum dial with improved precision adjustments. Updated soft lace cable for secure retention.
  • Simplified Internal Layout: A single main open compartment with flat lid pocket keeps essential tools organized and easy to access.
  • Hypalon Strap: Durable, high grip interface for stable mounting.
  • Light / Camera Mount Strap: Secure mounting point for light or camera.

Specs:

  • Capacity: 0.4L (13.5 fl oz)
  • Dimensions: 128 x 60 x 91 mm (5.04 x 2.36 x 3.58 in)
  • Weight: 44 g (1.55 oz)
  • Materials: TPU composite fabric with RF welded construction
  • Closure System: BOA Li2 metal dial with TX4 soft lace cable system
  • Strap: Hypalon reinforced strap
  • Zipper: Water resistant YKK zipper

Shockingly roomy

I'll start with saying this is very much a "nice to have item", especially when compared against the original Mattone. That said, I was surprised when I moved my items from my Mattone into this Mattone Ultimate, and have more space. So for anyone seeking to just have a bit more space, or just a sleeker saddle pack, well worth it. I dinged a star on value only to acknowledge that the original can do the same job as this for the most part.

Not quite right now

I use an under saddle radar, but its rail bracket leaves no room for the wide Silca strap. I removed the bracket to make room. I threaded the strap through the pack's loop then over the saddle rails. The snazzy Kevlar loop then hooks on their pack, and the fancy aluminium boa knob snugs it UP. The pack needs to be accessed with its zipper, but it hangs top down, and the contents need to be caught as they fall out. Wouldn't it be cooler if the pack could be quickly released from the strap? It turns out another under seat pack has that feature. It's less expensive and has more room. It simply works. I use two of those. They're simply slick.

Expensive but worth it.

Super small but fits tire removal tools, a tube, electric pump and multi tool. The Boa is the best part making it very tight and streamline. No rattles.

Light weight and secure

I love these seatpacks. Lighter and sleaker than the old one and holds my stuff just as well.

Tiny but mighty

Really well made and looks great! I did need to order some smaller tools and tubes to fit it all but smooth sailing since then. Looking forward to finding out how it handles the wet.

Love it

On the bike it looks great. Nice and compact like it's barely there. The boa strap feels very secure

A bit cumbersome to get on and off, but I'm ok with that
