Can confirm Duluth is great. Even if made overseas I believe.

Just recently got several Buck Naked Bullpen. Amazing.

Thrifted some Ballroom Flex. Rugged, thick, heavy, comfortable, huge pockets.

More recently a long sleeve longtail, and a black Tshirt with breast pocket. All built like tanks.

Also even more recently some kind of less well built khaki type pant in gray...I don't think it's a fire hose pant, but whatever it was and whoever wore it, they wore the SHIT out of it. There's only a few noticable wear spots I'll be having fixed, then I'll dye it black, and it needs some alterations to fit a little better. Then it'll go at least 10 years I bet before any real signs of wear.

Like Carhartt (Which I don't ESPECIALLY recommend anymore, esp for the price) sizing is very generous and you may want to go over size down. (For shirts, get regular size in boxers.)

Carhartt may still be good for pants and coveralls but imo you can't beat Wrangler Riggs, or any solid nylon, cotton, or poly cotton canvas rip stop from a good brand. I've also got some cotton canvas tech pants from Wrangler from Ross recently and they're VERY solid. I DON'T recommend their regular jeans. There's a million models and makes and it depends on where it's made and where you buy...but I did find two very very well made pairs of jeans eventually, but they were too big so I retired them.

FWIW, I know people who claim quality has gone down, but I've tried plenty from LL Bean, and maybe it's vintage but still looks practically new, but still seems incredibly tough and solid and thick to me. Particularly their sweaters, polos, shirts, jackets. Just good ol thiiiick cotton.
