Carhartt Men's Relaxed Straight Rugged Flex Duck (Style 367H)

In this review of the Carhartt Men's Relaxed Straight Rugged Flex Duck Double-Front Dungaree, the bottom line is simple: these are heavyweight work pants built to withstand tough jobs while still allowing movement. The reviewer finds them ideal for tradespeople who need durable knees and a roomy cut without sacrificing flexibility. Constructed from a heavy 12-ounce duck with a touch of stretch, they combine serious abrasion resistance with surprising comfort, making them a practical choice for daily jobsite wear.

Key Features

• 12-ounce duck fabric: The thick cotton duck provides substantial abrasion resistance and structure that holds up to repeated wear on rough surfaces.
• Rugged Flex technology: A small amount of stretch lets the pants move with the wearer for easier bending and crouching on the job.
• Double-front knees: Reinforced knee panels protect against wear and accept knee pads through cleanout openings for longer life on hard surfaces.
• Relaxed straight fit: Sits at the waist with a relaxed seat and thigh to accommodate tools and offer unrestricted movement.
• Durable construction: Stitching and panel placement are designed for heavy-duty use, resisting tears and maintaining shape over time.

Who It's For

These dungarees are aimed at construction workers, landscapers, and anyone who spends long days on their feet doing manual labor. The combination of heavy duck cotton and a relaxed cut makes them especially suitable for people who carry tools, kneel frequently, or need pants that tolerate abrasion and frequent washing.

Those who should look elsewhere include wearers who prefer a slim, fashion-oriented fit or lighter summer-weight pants for hot climates. If near-zero weight or highly breathable synthetics are priorities, a different work trouser would be a better match.

Pros & Cons

Pros

• Very durable 12-ounce duck fabric stands up to heavy use without thinning quickly.
• Rugged Flex stretch gives noticeable ease of movement for bending and climbing.
• Double-front knees with cleanouts accept knee pads and extend service life in high-wear areas.
• Relaxed seat and thigh provide room for tools and comfort during long shifts.

Cons

• Heavier weight makes them warmer in hot weather and slower to dry after washing.
• Relaxed straight cut may feel bulky to those who prefer a slimmer silhouette.

Frequently Asked Questions

The double-front knee panels include cleanout openings that accommodate knee pads and protect the knees during heavy kneeling.

Do these pants stretch for easier movement?
Yes, the Rugged Flex technology with 1 percent spandex provides durable stretch that helps when bending and moving on the job.

Will the heavyweight fabric be too hot for summer?
The 12-ounce duck is thick and will feel warmer than lighter work pants, so they may be less comfortable in very hot conditions.
