Most work garments list a number in ounces somewhere in the description, and most people scroll straight past it. That number predicts more about how the piece will feel on a job than the fiber content does.

Work pants get fitted around hardware. A belt, a set of boots, and whatever you hang off your waist all change the numbers, and none of that is accounted for by the size printed on the pair you bought five years ago.

A workday rarely stays at one temperature. You start in the cold, warm up inside an hour, and cool down again the moment you stop. Layering is how people deal with that, but done carelessly it turns into a stack of fabric that fights every reach and pull.

Work clothes do not get generically dirty. They get grease, or sweat salt, or clay, or a stripe of caulk down one thigh, and each of those needs a different first move. Throwing all of it into the same warm cycle is why so many good shirts end up with a shadow that never quite leaves.
