Should I use 1000D Cordura or 600D polyester?
Use 1000D Cordura nylon for tool bags, cases and covers that drag, rub and take abuse: it is far more abrasion and tear resistant. Use 600D polyester for promotional bags, covers and light-duty soft goods: it costs much less, holds color better in UV, absorbs less water and prints well. 1000D weighs about 10–12 oz/yd² (340–400 g/m²); 600D about 6–9 oz/yd² (200–300 g/m²).

Which should you pick?
Pick 1000D Cordura when
- Tool bags and pouches carry heavy or sharp tools
- The product is tactical, duty or equipment gear
- Covers drag across concrete, steel or gravel
- Workwear needs reinforcement panels
Pick 600D polyester when
- The product is a promotional tote or drawstring bag
- Outdoor covers must hold color in sun
- Budget drives a light-duty soft good
- Graphics are dye-sublimated or heavily printed
Key differences
| 1000D Cordura | 600D polyester | |
|---|---|---|
| Fiber | Air-textured nylon 6,6 | Polyester, usually oxford weave |
| Abrasion resistance | Very high | Much lower |
| UV and color stability | Fades and weakens with long exposure | Better |
| Water absorption | Higher; relies on a PU back coating | Low; dries quickly |
| Coating | Polyurethane back coat typical | PU or PVC; specify phthalate-free PVC for consumer goods |
| Printing | Screen printing and heat-applied labels | Screen printing, heat transfer and dye sublimation |
| Fabric weight | About 10–12 oz/yd² (340–400 g/m²) | About 6–9 oz/yd² (200–300 g/m²) |
Questions
Is Cordura worth the extra cost?
For bags and covers that are dragged, loaded with tools, or used daily on job sites, yes: abrasion sets their service life. For promotional and light-duty bags, 600D polyester delivers the look at a fraction of the fabric cost.
Are Cordura or 600D polyester bags waterproof?
Coated versions of both resist water, but stitched seams leak. A finished product is waterproof only with taped or RF-welded seams, usually on TPU-laminated or vinyl-coated fabric.
What does the D in 1000D and 600D mean?
Denier: the mass in grams of 9,000 meters of yarn. Higher denier means heavier yarn. Denier describes yarn, not fabric weight, so compare oz/yd² and coating too.
What about 500D Cordura?
500D weighs about 6–8 oz/yd² (200–270 g/m²) and is more flexible while still very abrasion resistant. It is the common choice for packs and apparel; 1000D is for bags and cases that take the hardest wear.
