Found these bike bags recently made by Swift Industries. They look quite nice and offer similar designs to the traditional cotton bags from Berthoud and Carradice.
I haven’t tried one, but I thought they were worth a mention if you are shopping for a bike bag and want to get something non-traditional and non-Ortlieb.
If you’ve got a Swift bag leave me a comment with your impressions. I’d be interested to hear what you think.
