Carhartt Men's B111 Flannel Lined Washed Duck Loose Fit (Style GTZ2)

Our review of the Carhartt Men's B111 finds these washed duck dungarees aimed squarely at people who work in cold, hands-on environments and want long-lasting comfort. The single biggest reason to buy is the flannel-lined construction: a 3.8-ounce cotton flannel lining over a 12-ounce ring-spun cotton duck shell that keeps heat in without feeling bulky. For those who need tool pockets, reinforced areas, and a roomy cut that fits over boots, this pant delivers practical warmth and utility rather than fashion-forward tailoring.

Key Features

• Heavyweight duck: The 12-ounce ring-spun cotton duck shell stands up to abrasion and repeated wear while remaining breathable for active tasks.
• Flannel lining: The 3.8-ounce cotton flannel lining provides measurable warmth and a soft interior against the skin for cold conditions.
• Loose fit: Sits slightly above the waist with a generous seat and thigh to allow layering and freedom of movement on the job.
• 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 cut to fit over work boots so there is no bunching or restriction at the ankle.

Who It's For

These pants are best for tradespeople, landscapers, and anyone who spends extended time outdoors in cooler weather and needs rugged, warm workwear. The combination of heavyweight duck and a flannel lining makes them ideal for winter job sites, early-morning chores, and layered outdoor work.

Shoppers who prefer a modern slim fit or need precise sizing for tailored wear should look elsewhere, since these dungarees are intentionally cut with a roomy seat and thigh and some customers report mixed feedback on exact sizing and length.
