Carhartt Men's 106679 Loose Fit Firm Duck Double-Front

In this review of the Carhartt Men's 106679 Loose Fit Firm Duck Double-Front Utility Work Pant, the bottom line is simple: these pants are built for heavy work and last. Designed to sit above the waist with a generous fit through the seat and thigh, they give plenty of room to move while the double-front knees add durability where jobs demand it. The single biggest reason to buy is the heavy-duty construction and double-layer knee protection, which make them a practical choice for mechanics, welders, and tradespeople who need long-lasting, functional work trousers.

Key Features

• Sits above the waist: Provides a traditional work pant rise that stays comfortable when bending or reaching on the job.
• Generous fit through seat and thigh: Allows freedom of movement and layers underneath without feeling restrictive during extended workdays.
• Double-front with cleanout openings: Reinforced double-layer knees protect against wear and accept knee pads for tasks that require kneeling.
• Multiple tool and utility pockets: Keeps essential tools and supplies organized and within easy reach while moving around a worksite.
• Left-leg hammer loop: Adds quick access for a hammer or similar tool so hands stay free when not in use.
• Durable duck fabric: Thick material resists abrasion and stands up to heavy use in tough environments.

Who It's For

These pants are aimed at tradespeople who need rugged, no-nonsense workwear: welders, carpenters, mechanics, and maintenance staff who value durability and utility pockets. The loose fit and straight leg opening make them suitable for wearing over insoles or with boots on long shifts.

Workers who prefer a modern slim fit or need precise sizing should look elsewhere, as customers report mixed sizing and a firm, stiff feel out of the box that softens with use. If you need a lightweight pant for hot-weather comfort, these thick duck fabric pants may be heavier than desired.

Pros & Cons

Cons

• Sizing can be inconsistent and some customers find them long or running big, so trying a size is recommended.
