Well I have a personal fondness for New Balance, all made in America to damned fine standards. I still have some NB sneakers I got about 14 years ago. They've seen me through 14 years of general use as well as 6 years in military PT.
I miss old Levi's, they aren't what they used to be. If you can still find a pair from 20 years ago like I've got in my closet, they're excellent quality. LL bean is good, though a lot of their stuff is made in China, albeit higher quality (at least for shirts). You pay for them though, about $20 each, but they last a few years. Wigwam makes some of the best socks I've ever owned. Made in USA as well. Takes me 4-6 years to wear down a pack. If I dug around I'm sure I could find a handful more decent brands of stuff. Not everything I have is great quality of course, but the GF tends to buy things he likes rather than specifically high quality, that's more my bag. She has had endless complaints regarding jeans shopping, which is almost universally trash now.
To be clear I'm not some xenophobe, I don't have a specific issue with globalization or things made in eastern Asia, aside from America generally exporting the cost of cheap labor to foreign countries. My issue is when those countries turn around and export the cheapest goods imaginable, designed specifically to wear out in a season or two so they can be replaced.
