I’m going to use them across my tank for my USA & Canada trip as I’ll be needing some everyday items within easy reach. They are and simple to attach and remove. Less time messing about opening boxes behind you as it’s all with easy reach in front of you when sitting on the bike. They will also be handy for daily use to stuff my things in if I leave the bike to visit a museum or place of interest for a while.
They can also be attached to the pannier frame when the metal ones are not in use. They are versatile and provide easy access to everything you need when on the road!
