I didn't call them, but usually all Ortlieb products are made in Germany.
Because the drybags, bicycle bags and motorbike bags have an outstanding high quality you see them in use as well as in shops everywhere in Germany.
Slowly the first become round about 30 years old. And off course people notice that.
I ask because I'm a fan of ortlieb and quality straps. Alas no not made in Germany like most of their range
