What is duck canvas?
Duck is a tightly woven plain-weave cotton canvas. The weave is denser than standard canvas, which makes it wind resistant and highly abrasion resistant. The name comes from the Dutch word doek, meaning cloth — nothing to do with the bird.
How heavy is Carhartt duck?
Traditional Carhartt duck runs around 12oz per square yard, which is why a vintage jacket feels substantial in the hand. Current production uses lighter weights in many models for comfort and cost, which is a large part of why vintage pieces feel different.
Why does duck canvas fade the way it does?
The dye sits on tightly packed fibres. Abrasion removes dye from the raised points of the weave first, so fade appears exactly where the fabric bends and rubs — knees, seat, elbows, pocket edges. That is why a genuine fade map looks like a record of how someone moved, and why factory washes never quite replicate it.
What is the difference between duck and canvas on Carhartt labels?
Carhartt uses duck for the heaviest work pieces and lighter canvas weaves for warmer-weather and comfort-focused models. Duck feels stiff and structured from new; canvas is softer immediately and drapes more.
Does duck canvas shrink?
Yes, especially with hot water and tumble drying. Vintage pieces have usually already shrunk as far as they will go, which is why flat measurements beat the tag. Wash cold and hang dry to keep what you bought.
How long does duck canvas last?
Decades. Most vintage Carhartt in circulation is twenty to forty years old and still structurally sound. Failure points are knees, seat and cuffs — everything else outlives the wearer's interest in it.
