Single Fill Ducks are the lighter, more versatile cousins of the Number Ducks. Single yarns in both the warp and fill — lighter and more flexible than the plied Number Ducks, hence the name. Not as heavy. Not as intense. But they show up in more places than you’d expect. Upholstery. Aprons. Tote bags. Tarps. The kind of fabrics that don’t brag about themselves but somehow end up everywhere.
Weights run from 7 oz to 15 oz per square yard. Widths from 36 inches to 144 inches. And a small confession upfront: none of these fabrics weigh exactly what the name says. We’ll explain as we go.

7 oz Single Fill Duck — our most popular in the lightweight category.
A “7 oz” that’s actually about 6.5 oz/sq.yd — a naming quirk we’ve made peace with over 15+ years. Shows up in upholstery, tote bags, aprons, shoe liners, kitchen textiles, and home furnishings. The fabric equivalent of a character actor: never the lead, in every scene.
Where it goes: Upholstery. Tote bags. Aprons. Lamination. Shoes. Kitchen textiles. Home furnishings.
10 oz Single Fill Duck — our staple seller.
A “10 oz” that actually runs about 9.3 oz/sq.yd — same naming quirk as the rest of the line. Available in “A” grade (for dyeing) or “AB” grade (not for dyeing), plus a Zen 10 oz dyed stock program with 30+ colors for those who want their workhorse with some flair.
Where it goes: Tote bags. Agricultural covers. Aprons. Tarps. Safety vests. Drop cloths. Artist canvas. Machine covers.
12 oz Single Fill Duck — starting to feel less like a lightweight.
A “12 oz” that actually runs about 11.4 oz/sq.yd — we’ve stopped trying to explain textile math. This is where Single Fill Ducks start to feel like a material that means it: mining bags, industrial covers, agricultural tarps — the kind of applications where the fabric gets ordered, not admired.
Where it goes: Mining bags. Industrial covers. Nail aprons. Agricultural tarps. Drop cloths.
14.9 oz Single Fill Duck — genuine canvassy texture, eco-friendly.
A hybrid weave — plied yarns in the warp, single yarns in the fill — woven on old shuttle looms for a texture modern machines can’t quite replicate. A cotton-rich blend with recycled polyester (from plastic bottles), with higher tensile and tear strength than a 100% cotton equivalent. Takes coatings beautifully; dyeing is trickier.
Where it goes: Wax-treated tarps. Machinery covers. Cattle dust panels. Rugged outdoor applications.
