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

In this review the Carhartt Men's B111 Flannel Lined Washed Duck Loose Fit Pant is presented as a durable, work-focused option for colder months; the single biggest reason to buy is the combination of heavyweight duck canvas and a full cotton flannel lining that keeps heat in without sacrificing mobility. The reviewer found these dungarees most valuable for tradespeople and outdoor workers who need reliable warmth and plenty of pockets, and notes the construction leans toward functionality over fashion while still looking tidy enough for casual business settings when paired with the right top.

Key Features

• Heavyweight shell: The 12-ounce, 100% ring-spun cotton duck provides abrasion resistance and a sturdy feel that stands up to jobsite wear.
• Flannel lining: The 3.8-ounce, 100% cotton flannel lining adds dependable insulation and a soft next-to-skin feel for cold weather comfort.
• Roomy fit: Sits slightly above the waist with a generous seat and thigh, giving unrestricted movement for bending, climbing, and lifting.
• Work-ready pockets: Multiple tool and utility pockets plus a hammer loop keep essentials organized and within reach during a workday.
• Boot-friendly hem: The 19-in leg openings are sized to fit over work boots for full coverage and easier layering.

Who It's For

The B111 is best for tradespeople, landscapers, and outdoor laborers who need a rugged pant that stays warm in winter conditions; the combination of heavyweight duck and flannel lining makes it a practical choice for cold job sites. It also suits anyone who prefers a loose fit through the seat and thigh and wants multiple pockets for tools and everyday carry.

Those who should look elsewhere include shoppers who prefer a slim, fashion-forward cut or lighter all-season pants; the B111 emphasizes durability and insulation over a tailored silhouette and may feel heavy in mild weather.
