This handlebar bag is an insulated bag with a touchscreen phone pocket and a detachable shoulder strap. The accessory also functions as a bicycle basket. Insulation and material construction: The bag is made of a fabric called twill, a blend of three materials heated to a high temperature. The central insulating layer retains its shape and function even in rain, wind, or low temperatures. This construction prevents the contents from heating up or cooling down too quickly without the need for additional coolants or lining. Dual use as a handlebar bag or shoulder bag: The bag has buckles on both sides that allow it to be easily attached to the handlebars. By unfastening the buckles and attaching the included shoulder strap, the bag transforms into a portable shoulder bag. This dual design makes the bag suitable for both bike rides and walks or shopping trips after the bike ride. Storage compartments and organization: The top compartment is large and transparent with a touchscreen film, allowing you to use your phone without taking it out of the bag. Two mesh pockets on the inside provide space for small items such as keys, energy bars, or a wallet. A separate waterproof zippered compartment keeps sensitive items such as papers or electronics dry during a rain shower. Easy use of the closure: All zippers are connected with a high-quality nylon cord. This cord acts as a large pull tab, making the zippers easy to open and close even with thick gloves. No separate zipper clip is needed to access the bag's opening. The zippers run smoothly without snagging. Dimensions and carrying capacity: The main compartment measures 22 by 13 by 18 centimeters. Frequently used items such as a phone, wallet, keys, a power bank, or a small snack fit in this space. The bag's external dimensions are no larger than a standard handlebar bag, ensuring that the bag does not affect handling. The insulated layer takes up minimal extra space.
