## Overview

The SILCA MATTONE Seat Bag combines a compact 0.53L capacity with innovative dual compartments and a padded separator to prevent tool damage and noise. Featuring a full waterproof YKK zipper and an asymmetrical design, it offers quick, spill-proof access on the bike or when off. Its high-friction Hypalon strap paired with a BOA ratcheting closure delivers 15x the holding power of Velcro, ensuring a secure, vibration-proof fit under your saddle. Lightweight at 110 grams and finished in sleek black with reflective detailing, this seat bag is engineered for the discerning cyclist who demands organization, durability, and style.

## Description

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 ‘page’ separating it from the other side where you can store an inflator head, multi-tool, contact lens case, etc. The ‘page’ 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.

Review: Ajuste perfeito - Ajuste e ótimo, não fica balançando. Porém antes de comprar saiba que é bem pequena. Vai bem uma espátula, uma câmara reserva e CO2 apenas.
Review: Tiny but holds everything - The small is perfect for my needs. Figured I’d post this here since I had a bit on anxiety about whether or not to buy the small vs. the large. With the small I’m able to perfectly fit a ridenow TPU tube, 2x tire levers, Topeak mini tool and a cycplus AS2 Pro with the stem adapter. It all tucks neatly behind my seat.

## Features

- BIKE SEAT BAG: Designed with elastic walls to hold an inner tube, a CO2 cartridge, a bike tire lever set, CO2 regulator head, a multi-tool, and more with ease (accessories not included in bike bag).
- EASY ORGANIZATION: Unlike traditional bike storage bags, the Mattone bike bag has pockets to keep multi-tools and tubes separated to prevent rattling and damage caused by friction.
- QUICK ACCESS: The waterproof zipper and asymmetrical design allow the bicycle saddle bag to open completely and lie flat when off the bike, but also provides easy access when on the bike without spilling.
- DURABLE & SECURE: Features a strong, high-friction Hypalon strap with a BOA closure that uses a ratcheting mechanism for easy installation over seat rails, ensuring the bike seat pack won't creep or loosen.
- SLEEK STYLE: This under seat bag bag has a sleek black finish that allows it to virtually disappear under the saddle while still having a reflective SILCA shield that provides high visibility in headlights.
