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. ## Technical Specifications | Specification | Value | |---------------|-------| | Size | 0.53 liters | | Brand | SILCA | | Material | Nylon | | Vehicle Service Type | Bicycle | | Product Dimensions | 8L x 4W x 12H Centimeters | | Item Weight | 110 Grams | | Pattern | Solid | | Mounting Type | Seat Mount | | Capacity | 0.53 litres | | Closure Type | Zipper | | Handle Type | Web Handle | | Number of Compartments | 2 | | Pocket Description | Zippered Pocket | | Shell Type | Soft | | Manufacturer | shimano | | UPC | 850005186168 | | Global Trade Identification Number | 00850005186168 | | Item model number | 850005186168 | | Manufacturer Part Number | AM-BG-013-ASY-0100 | | Volume | 0.61 Litres | | Water Resistance | Waterproof | | Country of Origin | USA | | Item Weight | 110 g | ## Product Details - **Size:** 0.53 liters - **Brand:** SILCA - **Material:** Nylon - **Vehicle Service Type:** Bicycle - **Product Dimensions:** 8L x 4W x 12H Centimeters ## Images ![SILCA MATTONE Seat Bag + BOA Closure System + Full Waterproof YKK Zipper for on The Bike Access - Image 1](https://m.media-amazon.com/images/I/71dmXcvBrNL.jpg) ![SILCA MATTONE Seat Bag + BOA Closure System + Full Waterproof YKK Zipper for on The Bike Access - Image 2](https://m.media-amazon.com/images/I/818mE1K+eIL.jpg) ![SILCA MATTONE Seat Bag + BOA Closure System + Full Waterproof YKK Zipper for on The Bike Access - Image 3](https://m.media-amazon.com/images/I/817+xjRmlwL.jpg) ![SILCA MATTONE Seat Bag + BOA Closure System + Full Waterproof YKK Zipper for on The Bike Access - Image 4](https://m.media-amazon.com/images/I/91mLruK-wcL.jpg) ![SILCA MATTONE Seat Bag + BOA Closure System + Full Waterproof YKK Zipper for on The Bike Access - Image 5](https://m.media-amazon.com/images/I/71IkAHnqgbL.jpg) ## Frequently Bought Together - SILCA Mattone Under Seat Bag for Bicylces with Zipper and Waterproof zipper and BOA mounting system (Small, Black) - Multi Tool 19 Black Midnight Edition - CYCPLUS Tiny Bicycle Pump with Gauge, Max 120 PSI Electric Mini Pump, Auto Stop, with Presta and Schrader Valve for E-Bike, MTB, and Road Bike AS2 PRO(2025 Updated Version) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.it/products/294809039-silca-mattone-seat-bag-boa-closure-system-full-waterproof-ykk](https://www.desertcart.it/products/294809039-silca-mattone-seat-bag-boa-closure-system-full-waterproof-ykk) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-05-13*
