Carhartt Men's B111 Flannel Lined Washed Duck Loose Fit (Style 2L67)

Our review of the Carhartt Men's B111 Flannel Lined Washed Duck Loose Fit Pant finds it best for people who need a rugged, warm work pant that stands up to winter jobs. Built from heavyweight 12-ounce ring-spun cotton duck with a 3.8-ounce 100% cotton flannel lining, these dungarees deliver obvious warmth and durability without feeling overly bulky. The cut sits slightly above the waist with a generous seat and thigh for layering and freedom of movement, and the reinforced pockets and hammer loop make them practical for tradespeople who carry tools on the job.

Key Features

• Heavyweight duck: 12-ounce ring-spun cotton duck provides abrasion resistance and structure for demanding work environments.
• Flannel lining: 3.8-ounce 100% cotton flannel lining adds warmth across the legs while remaining breathable for active work.
• Work-ready pockets: Multiple tool and utility pockets plus a hammer loop keep essential tools organized and accessible on the job.
• Generous fit: Sits slightly above the waist with extra room in the seat and thigh to accommodate movement and layering over base garments.
• Boot cut leg: 19-in leg openings fit over work boots so the pant works with typical safety footwear.

Who It's For

These pants are aimed at tradespeople, outdoor workers, and anyone who spends long hours outside in cold conditions and needs durable, warm trousers. The combination of heavy duck cloth and flannel lining makes them particularly well suited to winter work where abrasion resistance and insulation are priorities.

Shoppers who prefer a slim or modern tapered silhouette, or who require a precise tailored fit, should look elsewhere because the loose fit and roomy seat and thigh are designed for utility rather than form-fitting style. Also, those who need ultralight or highly water-resistant outerwear should consider specialized shells instead of a cotton duck pant.
