The Azur Top Tube Phone Bag is a popular seller in our store, for a few reasons. Firstly, it has a very generous capacity for a top tube frame bag. With a 1-Litre capacity in the main compartment, you have plenty of room for storing a tube (or tubes), multi-tool, energy supplements, wallet, or whatever you like to have with you. The zipper extends around 3/4 edges, allowing you to flip the lid all the way open for assessibility. There is a separate secure velcro pocket for your mobile device, which is protected against the weather by a clear waterproof cover. This pocket is large to suit present-day phones (maximum screen dimensions 16 x 8cm). Lastly, this bag is super affordable, making it excellent value for your buck.
