What does pie overcome mean?

It means military uniform.

Parker’s name “PARKA” comes from the concept of military uniform. In extreme cold environments, the Eskimos innovatively used animal fur to create a fur jacket with a hood. Its unique design included a ring of animal hair surrounding the face to provide additional warmth and protection.

This leather jacket not only effectively resists wind and snow, but also provides excellent warmth retention. Over time, this design was adopted by the US military and provided to soldiers stationed in the Korean War for cold protection and warmth, thus officially naming it "Parka".
