Flame Resistant ! Size 31x30 Purchased these from my last employer, originally were rentals so they have a company barcode on the waste which I cannot remove but a shirt would most likely always cover that if it bothers you! Great affordable option for someone who needs goo work pants. I have like 10 pairs too many my loss is your gain😊 I’m modeling the pants with a pair I’ve deceive to keep so no items have been worn.
