I bought a pair of Levi's 501s for $22 on Black Friday. I like how they look, but the pockets are almost too small to fit my hands in. They're holding up well considering I washed them a few times.
Carharrts, I've only worn American-made ones. I just took apart my last pair after getting the 501s...don't think I'll be finding any more used American-made ones.
I'd get a new pair if I wanted to look nice.
Filsons tin pans, I've worn, but they were hand-me-downs, a little small. I didn't really have any use for them as I was not in a wet climate. I plan on getting a pair this Autumn for mushroom picking. They're really only practical if you're out in wet conditions. Make sure and order the leather cuffs if you do.
On the matter of the Warranty, I believe they guarantee your satisfaction, but that says nothing about replacement after normal wear. Don't you think if $150 got you a pair of tin pants for life there would be more people on that bandwagon?
I like wearing tight pants because they don't get caught on anything. I had a pair I made myself, but they weren't stretch material and didn't give me the full range of motion. I've got a pair of Dogpile Chaos000 pants; I like tight pants because they don't catch on anything, so I can hop fences and climb shit no problem. Not so tough, but ripped/patched pants are punker, right?
Dickies are durable and comfy, but they're too comfy for me, I feel like I'm wearing pajama pants.
