The Carhartt Rugged Flex Rigby Dungaree has been my default work pant for six months. I picked up two pairs at retail in early October 2025 to replace a worn-out set of B11 duck pants. The big bet was on the stretch fabric: would the cotton-spandex Rugged Flex hold up to the same abuse as traditional duck canvas? Six months in, the answer is mostly yes. The Rigbys have survived garage projects, fence post replacement, two days of demo work in a friend’s basement, and dozens of wash cycles without fraying or losing shape.
Why you should trust this review
I bought these pants at retail. I have worn Carhartt work pants for over a decade and have written long-term notes on the B11 and Double Front Dungarees. See our methodology page.
How we tested the Rigby
- 6 months of regular wear from October 2025 through April 2026
- Garage projects (concrete, wood, paint exposure)
- Fence post replacement and yard work
- Two days of basement demolition
- 30+ wash cycles in cold water with mild detergent
- Side-by-side comparison with B11 duck pants for mobility and abrasion
Who should buy the Rigby
Buy if you want a work pant that handles real abuse but moves with you on ladders, in crawl spaces, and during repeated kneeling. Buy if you find traditional duck pants too stiff. Skip if you face the heaviest abrasion conditions (welding, brush clearing, ranch work) where the burlier B11 weave lasts longer. Skip if you want a slim modern silhouette, the Rigby is cut relaxed by design.
Stretch fabric: where the Rigby earns its keep
The 98% cotton, 2% spandex Rugged Flex weave is the headline. The fabric stretches enough to allow full squats and ladder steps without binding at the knees or inner thigh. Compared to traditional 12 oz duck, the Rigby moves like a softshell. Importantly, the stretch has not collapsed after six months of wear and dozens of washes. Some 95/5 stretch jeans I have owned lose elastic recovery after a season; the Rigby has not.
Knee and abrasion durability
The Rigby uses a double layer at the knees on the reinforced versions (the standard Rigby is single-layer; I tested the Double Knee variant of the Rigby Dungaree for the heaviest tasks). After kneeling on concrete and pressure-treated lumber for hours, the knees show light surface fade but no fraying or hole development.
Fit, sizing, and inseam
The cut is Relaxed in the seat and thigh, straight through the lower leg. Order your normal waist size. Inseam shrinks about 1 inch after the first wash, so order one inseam longer than your standard. A 34 inch waist with a 32 inch inseam came out to roughly 31 inches after the first wash and held there.
Pocket layout
Two front pockets, two back pockets, one tool pocket on the right thigh, one hammer loop, and one phone pocket on the right hip. The phone pocket fits a Pixel 8 in a slim case. The front pockets are shallow and a full keyring rides up. For users who carry a folding knife and keys, a clip is helpful.
Wash durability
After 30+ wash cycles, the fabric retains its color and the seams remain tight. Fading is even rather than splotchy. The waistband has not frayed at the belt loops, which is a common failure point on cheaper work pants.
Verdict
The Rigby is the right work pant for the modern tradesperson and the weekend project warrior. For more options, see men’s pants reviews.

Should you buy the Carhartt Rugged Flex Rigby Dungaree?
The Rigby Dungaree is the modern Carhartt work pant. Cotton-spandex stretch fabric moves with the knees, the relaxed fit gives full squat range, and the Rugged Flex weave has resisted six months of garage and yard abuse without fraying. The pants run a touch shorter in the inseam after one wash and the wider knee can catch on tools. At 50 dollars, they undercut most premium work pants while matching them on durability.
Frequently asked questions
Is the Rigby worth $54 in 2026?+
Yes. For under 60 dollars, you get a stretch work pant that handles real abrasion and lasts several seasons. Pricier alternatives like Truewerk or 1620 Workwear add features but cost two to four times more.
Rigby vs Carhartt B11, which should I pick?+
Pick the Rigby for daily wear, mobility, and squat range. Pick the B11 if you face the heaviest abrasion (welding, deep brush, ranch fence work) where the duck canvas weave outlasts stretch fabric.
Do the Rigbys shrink in the wash?+
Inseam shrinks about 1 inch after the first wash and stabilizes after that. Order an inseam 1 inch longer than your normal pant size.
Are the Rigbys cut for layering with thermals?+
Yes. The relaxed seat and thigh leave room for a thermal underlayer in the 30 to 40 degree range without binding.
