I was gifted some pants from Duluth Trading Company a year ago and I've now spent a bunch of money with them twice.
They make the most comfortable underwear IN THE WORLD. They make jeans (in the USA no less) that don't compress your junk. Combine them and you're unbeatably comfortable from the waist down. They make work pants made from heavyweight canvas that are impossible to destroy.
They just started selling some sort of fancy new sweat-wicking keep-you-cool-in-an-oven material shirt. I live in Texas and find myself working outside a fair bit, so I'm giving that a shot too.
