The TwinZipper double pannier has color-contrasting zips and highlights as well as a playful print on the primary material perfecting an urban touch. It's incredibly easy to attach and remove from your bike. Just attach the bar connecting the two bags to the top and side of the gear rack. There's a pre-mounted UniKlip 2 adapter plate for easy and secure attachment to the gear rack. The main compartment opens wide and closes with a zip; there's also a front pocket with zip for securely storing everything that needs to be kept close at hand. Reflective elements and a rain cover made from 100% recycled polyester ensure greater visibility in low light conditions.
