Motorcycle seat bag with 15 litre capacity, waterproof polyester and PU construction, 30x28x21 cm dimensions, featuring reflective safety strips, multiple pockets, and adjustable hooks for use as a tank, tail, or crossbody bag.
Motorcycle Seat Bag with 15-Litre Capacity, Waterproof Build, and Reflective Safety Design

This multifunctional motorcycle bag offers riders a practical solution for storing personal items securely while on the road. Designed to attach to the tank, tail, or seat of a motorcycle, it provides substantial 15-litre capacity protected by water-resistant materials. The inclusion of a high-visibility reflective strip enhances safety during dawn, dusk, or night rides, making it a considerate choice for all-weather commuting or touring. Its straightforward installation system and convertible strap mean it transitions easily from a fixed motorcycle accessory to a portable shoulder bag.
Features and Construction

This bag combines practical storage features with motorcycle-specific design elements. Its construction prioritises utility, weather protection, and ease of use for riders who need reliable gear on their journeys.
Material and Build
The bag's outer shell is made from polyester and PU (polyurethane), a combination chosen for its water-resistant properties. This material composition helps shield the bag's contents from light rain and spray, a common consideration for motorcycle travel. The fabric is described as lightweight, contributing to the overall practicality of the bag without adding unnecessary bulk to your motorcycle's setup.
Size and Practical Fit
With external dimensions of 30 cm in length, 28 cm in height, and 21 cm in width, the bag offers a compact yet capacious form factor suitable for motorcycle mounting. The 15-litre internal volume provides ample space for storing personal items, from tools and documents to a change of clothes or snacks. Its size is designed to fit various motorcycle models without interfering with the rider's movement or the bike's controls.
Uses and Placement

This bag is designed for flexible placement on a motorcycle and adaptable carrying options off the bike. It serves both dedicated riding purposes and general carrying needs.
Event or Professional Use
For commuting, touring, or longer rides, the bag's waterproof characteristics and large capacity make it suitable for carrying essential items securely. The reflective safety strips provide an added layer of visibility, which is particularly valuable for professional couriers, daily commuters, or riders travelling in variable light conditions. The multiple internal pockets allow for organised storage of items like phones, wallets, keys, or small tools, keeping them accessible but secure.
Everyday Home Use
When not attached to the motorcycle, the included detachable strap converts the bag into a practical shoulder or crossbody bag. This dual functionality means it can be used for everyday errands, short trips, or as a general-purpose carryall, maximising its utility beyond motorcycle-specific scenarios. The same organisational pockets that help on the bike remain useful for keeping everyday carry items sorted.
Benefits and Buying Value

The value of this motorcycle bag lies in its multifunctional design, protective features, and thoughtful safety elements. It addresses common rider needs without requiring specialised maintenance.
Reuse and Low Maintenance
The bag's polyester and PU construction is straightforward to care for, requiring only occasional wiping with a damp cloth to clean. Its durable fabric and robust hook attachment system are designed for repeated installation and removal, supporting regular use across different motorcycles or carrying scenarios. The convertible design extends its usable life beyond single-purpose motorcycle accessories.
Why Choose This Product
This bag offers a combination of specific features that cater to motorcycle riders: substantial waterproof storage, safety-enhancing reflectivity, and flexible mounting options. Its 15-litre capacity provides a practical middle ground between small pouches and larger luggage, suitable for day trips or commuting. The inclusion of both motorcycle attachment hardware and a shoulder strap delivers versatility that adapts to different travel needs, from riding to walking.
