Review on 🔲 Large Black Zefal Bag Z Box by Holly Robinson

Large size for added versatility. Use with or without an extension tube that has a neat unscrewable "bottom" to form a separate compartment if desired. The secure top will not come off or fall off while driving. Fits most bottle cages, but before you head out onto rough roads, make sure it's secure. It easily fits a travel snorkel, mini tool, and CO2 blower, leaving room for other long-haul essentials. Many prefer this to a seat bag with similar storage capacity. NOT suitable for a typical smartphone, but then none of these "boxes" will fit.
