Here's our slightly lighter-weight 9.5-ounce cotton drill work overall. Like all of our overall designs, you can count on plenty of handy tool and utility pockets and, of course, a hammer loop. This overall also features tough double knees with cleanout bottoms designed to accommodate knee pads. Although it's made of a slightly lighter-weight material, this overall has been thoroughly fabric-tested for strength and wear-resistance. After all, a tough, long life is something you can always count on with Carhartt!For over 115 years, Carhartt has manufactured premium workwear known for exceptional durability, comfort, quality of construction, and fit that you can feel in the fabrics and see in the performance.
