## Overview

The SILCA MATTONE Seat Bag combines innovative organization with rugged durability in a sleek, compact 0.53L design. Featuring a waterproof YKK zipper and a BOA ratcheting closure system 15x stronger than Velcro, it secures your essential bike tools without rattling or loosening. Its asymmetrical zipper allows quick access on the bike, while the reflective SILCA shield enhances visibility, making it the ultimate under-saddle companion for serious cyclists.

## 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.

## 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.
