Cycling tail bag waterproof large capacity 13L tool storage PVC construction outdoor bike luggage rear rack bag in black, green, or yellow
13-litre waterproof cycling tail bag for outdoor bike gear storage

Carrying spare tubes, tools, snacks, and personal items on long rides requires reliable, weather-protected storage. This tail bag attaches to your bicycle's rear rack, providing a dedicated 13-litre compartment constructed from PVC material. Its waterproof nature ensures your essentials stay dry in rain or wet conditions, while the practical dimensions offer a spacious yet streamlined profile. Offered in black, green, and yellow, it suits different visibility needs and style preferences for cyclists.
Features and Construction

This bag is designed with a focus on practical utility for the cyclist, combining specific materials and dimensions to serve its outdoor purpose.
Material and Build
The bag's main body is made from PVC, a synthetic plastic polymer chosen for its inherent water-resistant properties. This material choice forms a waterproof shell that prevents rain and road spray from reaching the contents inside, a key consideration for outdoor cycling. The construction focuses on creating a sealed storage environment, with the PVC offering a degree of rigidity to help the bag maintain its shape when loaded with items like tools or clothing.
Size and Practical Fit
With external dimensions measuring 58cm in length, 16cm in width, and 20cm in height, plus a 6.5cm depth, the bag provides a substantial 13-litre cargo volume. This capacity is suitable for a range of cycling gear, from a compact toolkit and tyre levers to a waterproof jacket and energy bars. The elongated shape is designed to fit neatly on standard bicycle rear luggage racks, distributing weight low and to the rear of the bike for stable handling.
Uses and Placement

Its design is centred on the specific activity of cycling, providing a storage solution that integrates with your bike's existing hardware.
Event or Professional Use
For longer touring trips, sportives, or bikepacking adventures, the 13-litre capacity allows for carrying essential spare parts, a multi-tool, a mini-pump, and extra layers without needing a backpack. The waterproof PVC construction is particularly valuable for multi-day events where weather can change, ensuring electronics, maps, or dry clothes remain protected from unexpected showers or river crossings.
Everyday Home Use
For daily commuting or recreational rides, the bag offers a secure place for a lock, lights, a change of shoes, or groceries. Mounting it on the rear rack keeps the load off your back, improving comfort and ventilation. The choice of black, green, or yellow allows it to match different bike frames or provide high-visibility safety colouring for urban commuting in lower light conditions.
Benefits and Buying Value

The value of this product lies in its dedicated function and the practical benefits derived from its stated specifications and material.
Reuse and Low Maintenance
The PVC material is straightforward to maintain; surface dirt can be wiped away with a damp cloth, and its waterproof nature means it does not require separate rain covers or internal dry bags for basic wet-weather protection. This reusability across many rides, from short commutes to long tours, provides ongoing utility from a single product.
Why Choose This Product
This tail bag presents a focused solution for cyclists needing a specific capacity—13 litres—and a confirmed waterproof material—PVC. The provided dimensions allow you to assess its fit on your rack and its capability to hold your required gear. The availability of three colours offers a choice between subtle integration (black) or increased visibility (green, yellow), letting you select based on your practical needs rather than a single default option.
