A side bag designed for holding a passport and mobile phone should have specific features to ensure both items are secure and easily accessible. Here are some features you might look for in such a bag:
Compartments: Look for a bag with separate compartments or pockets to keep your passport and mobile phone organized and protected. A dedicated slot for your passport helps prevent it from getting damaged or mixed up with other items.
Secure Closure: A bag with a zipper or a secure flap will help keep your items safe. Some bags also have additional closures like magnetic snaps for added security.
Size and Fit: Given the dimensions you mentioned (23x28x8 cm), ensure that the internal layout of the bag accommodates your passport and phone comfortably without excessive space that could lead to shifting.
Material: Rexine leather is a good choice for durability and ease of maintenance. It should be easy to clean and resistant to wear and tear.
Adjustable Strap: An adjustable strap is useful for customizing the fit of the bag when wearing it as a side bag.
