Carhartt B111 Flannel Lined Washed Duck Loose Fit Pant

Our review of the Carhartt B111 Flannel Lined Washed Duck Loose Fit Pant finds it best for anyone who needs a rugged, warm work pant that performs outdoors in colder weather. Built from heavyweight 12-ounce ring-spun cotton duck and lined with 100% cotton flannel, these dungarees deliver consistent warmth and durability without feeling overly stiff. The cut sits at the natural waist with a full seat and thigh and 19-in leg openings designed to fit over work boots, so the single biggest reason to buy is the combination of heavy-duty fabric and a full flannel lining that keeps you comfortable on long, cold jobs.

Key Features

• 12-ounce cotton duck: The heavyweight ring-spun cotton duck provides long-lasting abrasion resistance for daily workwear use.
• Flannel lining: The 100% cotton flannel lining adds warmth and a softer interior for comfort during extended outdoor tasks.
• Loose fit cut: The full seat and thigh allow a wide range of motion and accommodate layers underneath when temperatures drop.
• Work-ready pockets: Multiple tool and utility pockets plus a hammer loop keep tools and small items accessible on the job.
• Boot-friendly leg opening: The 19-in leg openings are sized to go over work boots so you do not have to worry about compatibility with protective footwear.

Who It's For

The Carhartt B111 is aimed at tradespeople, outdoor workers, and anyone who spends long hours in cold conditions and needs a pant that stands up to wear and tear. Its heavyweight duck cloth and flannel lining make it particularly appropriate for winter jobs like construction, farming, and outdoor maintenance.

Shoppers who need a slimmer, fashion-forward fit or who work exclusively indoors in mild climates may want to look elsewhere; customers seeking precise sizing may also want to try these on first, as fit and length have received mixed feedback.
