Description
The Silca Mattone Ultimate Seat Bag is a compact, 0.4-liter under-saddle storage solution designed for road riders and performance cyclists seeking essential carry capacity with a low-profile fit. Made from laminated TPU composite fabric with RF welded exterior panels, it offers a smooth, weather-resistant shell that fits tighter under the saddle than traditional seat bags.
The bag features a clamshell opening revealing a single main compartment and a flat lid pocket, ideal for organizing and accessing essentials such as a tube, tire lever, inflator, and multi-tool. It uses a BOA Li2 closure system with a low-profile aluminum dial and TX4 soft lace cable for secure and precise adjustment without added bulk.
The Hypalon reinforced mounting strap ensures durable and high-grip attachment to the saddle, with an integrated loop for attaching a light or camera. A water-resistant YKK zipper helps limit moisture entry at the main opening. The seat bag weighs 44 grams and measures approximately 13 x 6 x 9 cm. It is black in color.
