I'm a framer, for context. So my pants are weighed down with a square in my back pocket, a hammer in the loop, a heavy duty belt, a tape measure on that, a pocket full of screws/nails/bits/etc, my phone, a utility knife, a pocket flashlight, pencils, etc.
The fit, the amount of pockets, and fabric is fantastic. I ordered an 8, and they fit perfectly. The drawbacks:
1. The pockets honestly need to be a little deeper, my phone barely fits.
2. I have to wear a long shirt with them to tuck into the waistband or else they rub on my hips with all the weight, and by the end of the day, my skin is red and sore. I'm thinking this could be fixed by adding a bit of flex to the waistband, so that it moves with you during the day and doesn't just dig in.
