As an owner of Ortlieb panniers, Sport-Packer Plus front panniers and Bike-Packer Plus rear panniers I honestly hadn’t really considered what the names mean but clearly it was causing confusion somewhere as Ortlieb USA have published a nice little graphic explaining the pannier names. The only problem with their graphic is that they seem to have the Sport-Packer Plus panniers as rear panniers when these panniers are really front ones; they have a capacity of 30 litres compared to the Bike-Packer Plus, the rear panniers which have a capacity of 42 litres. Anyway the chart is handy guide to your way around Ortlieb panniers despite this little error.

Ortlieb Pannier Names
Great find. I had no idea that Ortlieb had a system but I guess coming from a German company, it only makes sense.
Nice to know what the names mean for sure.
