Weird, Bombas doesn't show as being made in the U.S. Darn Tough says they are made in Vermont. Smart Wool says Tennessee and North Carolina.I have a brother in law that worked for smartwool so I have a pile of good socks. This Christmas he gave me some darn tough socks. I looked at him confused and said what about smartwool? He said all those kinds of socks that style are made in the same place, they just change the name. Bombas, darn tough, smartwool, and many others are the same socks.
