    Seat bag users fall into two categories: Seat roll aficionados and seat bag users.

    Traditionally, seat bags have been simple open spaces that allowed content to jangle about, making noise and rubbing against each other. Often times a spare tube was pulled out of a seat bag to reveal it was more full of holes than the tube being replaced due to friction against a house key or multi-tool. With Mattone, we designed a layout similar to a book, where the bag can fully open to hold the tube and CO2 cartridge on one side, separated by a padded ballistic nylon ‚ separating it from the other side where you can store an inflator head, multi-tool, contact lens case, etc. The flap also contains a slot for a credit card, ID, money, or house key. The unique off-center Aquaguard Zipper allows the case to completely open and lay flat when off the bike, while also allowing easy access to the multi-tool and money/card slots when on the bike without risk of spilling all the contents of the bag.

    A high friction Hypalon strap with BOA® Closure completes the package. Making more than 15x the power of Velcro®, the BOA® Closure uses a ratcheting mechanism that will not creep or loosen even under the most extreme vibration and impact. This ensures the Mattone will remain high and tight‚ under your saddle until you need to access it... no swinging, swaying, or rattling... ever!

      Secure & Unobstructive

      Running this on a hardtail with a dropper. Keeps CO2, filler head, levers, patch kit, and ID/cards where they belong. Also stays where it belongs overall and accommodates the dropper nicely. Prefer it for riding in drier conditions. If you have a soaking ride, pull it and make sure everything gets dry. Will see how the BOA lasts long term, but for now, it does its job.

      Way too small

      This is ridiculously small. A 27,5 gravel tube fills all the available space with literally nothing left for anything else.

      I'm seeing that they're pushing this for gravel but this is impractically small for anything useful.

      Size of the bag is a tricky one. To use the mattone well for gravel, it is ideal to use the TPU tubes. We regularly see two 700x42 tubolito's plus the rest of a flat kit, but a single butyl tube can also take up all the space.

      Perfectly compact

      I have a tube, 2 CO2 cartridges, the adapter, and 2 tire levers fit inside. The Boa system keeps it secure under the saddle. Very happy with the purchase.
