About Product
#4 Cotton Duck Canvas – 24 oz Natural Heavyweight | 100% Made in USA | Berry Amendment Compliant
When you need the toughest, most authentic heavyweight canvas on the planet, accept no substitute: our #4 cotton duck (24 oz) is woven in the USA from 100% American-grown cotton using ultra-strong 5-ply yarns in a double-fill construction. This is the real-deal numbered duck that built America’s tents, wagon covers, conveyor belts, and military gear for over a century.
At a massive 24 ounces per square yard, this is one of the heaviest all-cotton ducks you can still sew without specialized equipment — yet it remains surprisingly workable on a good walking-foot or industrial machine. The tight, rugged weave delivers legendary tear strength, abrasion resistance, and longevity that modern lightweight fabrics simply can’t match.
Why Marsidian #4 24 oz Cotton Duck Beats Every Import & Even Most “American” Brands
- Truly 100% Made in USA from U.S. cotton (most competitors finish imported greige goods)
- Full Berry Amendment & Buy American Act compliant – perfect for DoD, USPS, and government contracts
- Massive 60" usable width (most sellers only offer 36–48") → fewer seams & lower labor cost
- Double-fill (#4) construction with 5-ply yarns = dramatically higher strength than single-fill 24 oz
- Classic natural undyed/unbleached color – ready for dyeing, waxing, or use as-is
- Proven in the harshest environments: foundries, farms, archery ranges, stage rigging, and marine use.
