Engineered for extreme-duty performance, our 680 GSM Cotton Canvas fabric (20.1 Oz) represents one of the heaviest and most durable constructions in cotton canvas. Crafted from 100% premium cotton with a thick yarn configuration of 3/7 × 3/7, this fabric delivers exceptional bulk, toughness, and long-term resilience.

Built on a 40 × 22 (EPI × PPI) weave and a standard 60-inch width, it offers a powerful structure with 680 GSM / 1035 GLM / 20.1 oz/yd². The combination of heavy yarns and balanced construction creates a canvas that is highly resistant to tearing, abrasion, and load stress, making it ideal for industrial covers, truck tarpaulins, heavy-duty tents, protective equipment, and rugged outdoor applications.

What sets this fabric apart is its solid hand feel and structural stability—it holds shape under pressure while still allowing workable flexibility for manufacturing and stitching in demanding product categories.

Offered in Conventional Cotton, Organic Cotton, Pre-consumer Recycled Cotton, Post-consumer Recycled Cotton, and BCI Cotton, all variants comply with OekoTex Standard 100, ensuring the fabric is free from harmful chemicals and safe for use.

For bulk handling and export efficiency, the fabric is securely roll-packed up to 500 meters, maintaining edge integrity and protecting against moisture and contamination during transit.

Supported by globally recognized certifications such as GOTS, GRS, RCS Blended, OCS 100, and OCS Blended, this canvas guarantees traceable sourcing, sustainable production, and verified quality standards.

If your application demands maximum strength, high abrasion resistance, and uncompromising durability, this ultra-heavy cotton canvas is built to perform in the toughest conditions.
