Duluth Fire Hose Flex 45507 have held up well for me, so much so that I have 7 pairs. The only crotch I had get damaged was when I got them hooked on a scaffolding platform hook. My Keybar did wear through the back pocket from moving around on masonry. I am probably going to start switching over to a heavier weight 92204.

I would like to try out the Alec Steele 01 G1, but they sell out fast and runs are infrequent.

Carl Murawski made a video in a similar style to ProjectFarm comparing different brands of workpants.

ProjectFarm themselves did a couple videos testing the durability between different brands of jeans. The first one focuses on affordable jeans, while the second video throws in expensive brands as well to see how they compare.

Interestingly, the dickies ProjectFarm tested seemed to do quite well regarding crotch tearing, and did okay on the abrasion test. If your pants material is failing due to thinning out from abrasion, I would guess that the ones that did well on both the abrasion test and crotch tear test would be your best bet.

My dad swears by Duluth stuff.

Buddy of mine swears by 5.11 pants

Idk if they ship to Canada or not.. good luck op!

Pants will wear out. I wear Carhardt washed twill pants every day. They hold up really well for heavy jobs, but won't last forever. I have several pairs that are ratty and reserved for extra dirty work. At most, they last me 2 years before they look like hobo pants.

I don't like the cut of dickies, and they aren't as tough as the carhardt washed twills.

The washed twills are $35-50 US. Beyond these pants, everything else is a trade-off. Better pants, kuhl, 5.11, Deluth, heavy duty Carhardt Duck; all more expensive, some to a laughable extent.

Come join the Carhardt gang.

Just FYI, not all Dickies are created equally. They sell lower quality ones at places like Walmart. The material is thinner and the stitching uses thinner thread and a different stitch pattern.

I still wear some Dickies I bought 25 years ago.

Carhartt, just make sure it's pants that are supposed to be "work" pants. It's become a fashionable brand now, so I think they make a lot of casual clothes.

Duluth firehose pants are definitely good.

A couple brands I haven't seen mentioned yet:

ArborWear, who specializes in logging apparel makes good tough canvas pants, and they are affordable for what you get. I have a flannel lined pair that are very close to being stiff enough to stand up on their own.

Filson pants cost an arm and a leg, but should be good from what I've seen.

Basically, you want real, non-stretch jeans or canvas. Bonus if they tell you the weight of the fabric. Once you get any spandex in there, you are limited in strength. I also always go for pants with reinforced crotches, cause otherwise that fails first for me.

blaklader!

I've heard good things about SOSO 33oz, not tried them personally though.
