Some fabrics are built to go outside. These are built to stay there. Salt spray. Gale winds. Sun that doesn't quit. They're not coming inside. Neither is the weather.
We carry two finishes: DWR (water and mildew repellent) and FWR (water, mildew, and flame retardant per CPAI-84). Both are built on 100% Cotton Army Ducks woven with ring-spun yarns. Longer fibers. Stronger fabric. Most of the fabrics out there use open end yarns with short fibers. Ours doesn't. End result: a fabric that takes a beating from the elements and stays strong.
It also comes with a taped, tucked-in selvedge — not a fringe, not a leno edge. That's not a small detail. A leno edge unravels under tension and open weather. A tucked-in, taped selvedge doesn't. If you sew, you know why that matters. If you don't, trust the people who do.
Preshrunk to less than 3% residual shrinkage. Because surprises are for birthdays, not boat covers. Yes, we tested it. Yes, it passed. Lab reports are downloadable below where we've got them on file. Additional test reports available on request.
The finish is dry. Odorless. Unlike the waxed fabrics down the hall. VAT dyed, which means the color goes deep and stays there. Water rolls off. Mildew gives up. Rot doesn't start. PFAS-free. Prop 65 compliant. EPA standards met. All the good stuff. None of the bad.
Where it goes: Boat covers. Bimini tops. Tents. Glamping tents. Wall tents. Tipis. Yurts. Awnings. Camper tops. Mooring covers. You know this fabric. You've been using it for years. We didn't improve it. We didn't need to. We just have it.

Values shown are from our Colorless colorway lab reports (NTRC Report No. 15-015511, dated 01-Sep-2025, and SGS Report No. LAHSL260001697, dated 16-Mar-2026) and are representative of this construction across the line. Minor variation is normal between dye lots and colors.
