Depends upon the pants and the days in question

Weekends I’ll wear the same jeans, fold em up and put em in the drawer for the next weekend.

Same with my work clothes. I have dress pants hanging in my closet that haven’t been washed in many days of wearing. If they’re not dirty why wash em?

Of course I’ll wear work pants in the yard or fishing/hunting and get em filthy with dirt and blood and wear em a couple days since they’d just get dirty again if I washed em.
