Was made in the US Coach bags/briefcases on par with Made in US Ghurka?
No. Coach was known for sort of thick, durable, no-nonsense quality. I think Ghurka aimed for better detailing and finishing.
I have a Ghurka planner I've used since 1996. Still going strong.
I had a Ghurka wallet fall apart in two years, but I wore it hard.
