Carhartt Men's B111 Flannel Lined Washed Duck Loose Fit Pant

Our review of the Carhartt Men's B111 Flannel Lined Washed Duck Loose Fit Pant finds it best suited for anyone who needs a rugged winter work pant that keeps heat in without sacrificing durability. Built from 12-ounce ring-spun cotton duck with a full cotton flannel lining, these dungarees are primarily worth buying for the reliable warmth and long-lasting construction they deliver on outdoor jobsites or in cold workshops.

Key Features

• 12-ounce cotton duck: The heavyweight construction provides a sturdy shell that stands up to abrasion and daily wear on the job.
• 100% cotton flannel lining: The flannel lining traps warmth and adds comfort against the skin for cold-weather work.
• Loose fit with full seat and thigh: The roomy cut allows freedom of movement for bending, climbing, and working with tools.
• Utility pockets and hammer loop: Multiple tool pockets and a hammer loop keep essentials close at hand for hands-on tasks.
• Reinforced back pockets: Extra reinforcement extends the life of high-wear areas where tools and wallets sit.
• 19 in leg opening: The wide hem is sized to fit comfortably over work boots without restricting movement.

Who It's For

This pant is aimed at tradespeople, landscapers, and anyone who spends long hours outdoors in cold weather and needs work-ready pants that hold up to heavy use. The full flannel lining and heavyweight duck make it particularly suitable for winter jobs, shoveling, and cold-climate construction work.

Those who prefer a slimmer, more tailored silhouette or lighter, packable layers for intermittent cold may want to look elsewhere. If precise sizing or a trim fit is essential, be aware some customers mention mixed feedback on sizing and length, so trying them on or checking fit guidance is wise.
