CarharttMen's Flame-Resistant Midweight Canvas PantLoose Fit

These pants are great, fit and finish are good, they run a little small and need to go to the next waist size. Good quality material excellent for work

As other people mentioned (and I failed to see before buying), these run about 2" smaller around the waist

I have worn the B159 and FRB159 for about 5 years for work. Very comfortable. I often wear them to other places other than work.
