I'd be surprised if anything with a Timberland label on it now is made in America. Same with most other clothing brands . Some stuff will, same as some gear is still made in the UK, but really small amounts in the grand scheme of things.I have a pair of Timberland walking boots that I bought in America in 2001.
They are great - comfortable & waterproof, and still going strong. (Not that I do much serious walking).
I also have some T-shirts and golf tops bought in America that have stood the test of time.
I get the impression that clothing in general that's made in the USA seems to be of a higher quality.
