Product Description

A convertible pannier bag backpack from FMOSBAG is a versatile 3-in-1 storage solution for daily bike commuting and long-distance touring. Built with high-density 600D PVC coated polyester, it uses a roll-top buckle closure for solid water repellency. It effectively protects belongings from rain and road mud splashes on every ride.

Waterproof & Durable Construction

The 600D PVC coated polyester fabric delivers better tear and scratch resistance than standard 500D materials. The roll-top sealed structure keeps internal items dry in heavy rain. The surface is also easy to wipe clean for long-term daily use.
