Cordura fabric: what it is, with nylon, Oxford and 500D compared
Nov
Cordura fabric is a brand, not a separate material: according to Wikipedia, it is a brand of synthetic fiber-based fabrics used in luggage, backpacks and military wear, and its fabrics are generally made of nylon. This guide explains what the words Cordura, nylon, Oxford and polyester mean on a bag, then compares six nylon and Oxford chest bags and crossbody bags from our men’s bags catalogue, read on 11 November 2026. What a listing does not publish, we do not claim: the cell says “not recorded”.
What is Cordura fabric?
Cordura fabric is a collection of abrasion-resistant fabrics used for luggage, backpacks and clothing. According to Wikipedia, DuPont developed and trademarked the brand in 1929, and it is now owned by Invista. The French-language page adds that it switched to nylon in 1966.
These everyday bags sit in our men’s chest bag range. The facts come from the Cordura page on Wikipedia and its French counterpart. Nylon itself is older: according to French-language Wikipedia, it was invented on 28 February 1935 by Wallace Carothers at DuPont (Nylon page). One practical consequence: a brand is licensed. A bag labelled “Cordura” uses that brand’s fabric; a bag that only says “nylon” or “technical fabric” does not guarantee it.
What does 500D or 600D mean on a bag?
The “D” stands for denier, a unit of yarn thickness. According to French-language Wikipedia, one denier is a mass of 1 gram for 9,000 metres of continuous yarn. A 600D yarn therefore weighs 600 grams per 9,000 metres: the higher the number, the thicker the yarn.
Source: the Denier page. Denier alone says nothing about final quality: it measures the yarn, not the weave, the coating or the stitching. Two 600D fabrics can behave very differently, so we do not rank bags on that number alone. Models announced as 500D or 600D are mostly tactical: see the men’s bags catalogue.
Cordura, nylon, Oxford and polyester: what is the difference?
Nylon is a fibre, polyester is another fibre, Oxford is a type of weave and Cordura is a brand. The four words are not on the same line: an Oxford fabric can be nylon or polyester, and a Cordura fabric is usually nylon.
- Nylon: a synthetic fibre. According to French-language Wikipedia, its low absorbency means it dries quickly.
- Polyester: another synthetic fibre, very common as lining. In our table, three bags out of six have a polyester lining under a nylon or Oxford outer.
- Oxford: a tight weave, widespread on city and tactical bags. Our Oxford fabric guide covers it.
- Cordura: the fabric brand described above. We hold no supplier certificate for any of our listings, so we quote the material as announced.
What do six catalogue bags say?
Of six catalogue listings, three announce nylon (one of them Cordura) and three Oxford, and only three give full dimensions. We have neither weighed nor measured these bags ourselves: the figures are those of the listings, read on 11 November 2026, and the outer volume is calculated (width x height x depth).
| Listing | Announced fabric | Lining | Size (cm) | Outer volume | Weight |
|---|---|---|---|---|---|
| Tactical chest bag “Rig” | Cordura nylon 500D, PU and DWR coated (listing text) | nylon | 20 x 15 x 5 | 1.5 L | 220 g |
| Military chest bag LXKB001 | Oxford 600D | not recorded | not recorded | not recorded | not recorded |
| Tactical chest bag ASB05 | Oxford | not recorded | 27 x 18 (depth not recorded) | not recorded | not recorded |
| Light Oxford chest bag | Oxford | polyester | not recorded | not recorded | not recorded |
| Mini nylon crossbody bag | nylon | polyester | 19.5 x 15 x 6 | 1.8 L | not recorded |
| Nylon climbing chest bag | nylon | polyester | 24 x 15 x 6 | 2.2 L | not recorded |
Two points stand out. First, these bags are small: 1.5 to 2.2 litres of outer volume, enough for a phone, keys and a wallet, not for a laptop. Second, the “Rig” listing announces Cordura nylon 500D while its material attribute says Oxford: without a supplier certificate we cannot confirm the Cordura name, and we suggest treating it as an indication.
Cordura or 600D Oxford: which holds up better?
No independent test lets us decide between the two on the bags in this catalogue. A higher denier (600D against 500D) does not guarantee better strength, because the weave, the coating and the stitching matter as much as the yarn.
What the listings say, unverified by us: the 600D Oxford model is described as water-repellent, so protected from light rain and splashes, and the “Rig” mentions a DWR and PU treatment that resists light rain. Neither is waterproof. A standard zipped bag lets water in through the seams in a long downpour anyway. For the full distinction, see our men’s bags catalogue and read each listing’s coating line.
Which fabric for which use?
For daily city use a light nylon or Oxford is enough; for tactical or outdoor use you look for a heavier fabric, so a higher denier, and a water-repellent treatment. Leather stays the choice for a dressier look.
- Daily commute: a 2-litre nylon bag from the men’s chest bag range keeps the phone and keys within reach.
- Hiking, cycling, fishing: the tactical models announce heavier fabrics and adjustable straps.
- Dressier look: choose leather; for faux leather, read what PU leather is.

Conclusion: read the announced material before the number
Cordura is a fabric brand, nylon is a fibre and denier is a unit of yarn thickness. For a bag, read the announced material, the lining and the size before comparing numbers such as 500D or 600D. The men’s bags catalogue lets you repeat this reading listing by listing.
Frequently asked questions
Is Cordura nylon?
Cordura is most often nylon. According to Wikipedia, Cordura fabrics are generally made of nylon, though they can be blended with cotton or other fibres. Cordura is a fabric brand, not a fibre.
What does 600D mean on a bag?
On a bag, 600D means 600 denier. According to French-language Wikipedia, one denier is 1 gram per 9,000 metres of yarn. The figure shows yarn thickness, not final fabric quality, which also depends on weave, coating and stitching.
Is a nylon bag waterproof?
A nylon bag is not waterproof by nature. Nylon absorbs little water and dries quickly, but a bag still lets water through at the seams and zip in a long downpour. Look for a water-repellent coating, and a covered zip if rain is frequent.
What is the difference between Oxford and nylon?
Nylon is a fibre, Oxford is a weave. An Oxford fabric can therefore be nylon or polyester. On our listings Oxford is announced without a specific fibre, which is a reason to read the description before buying.
Which fabric for an everyday bag?
A light nylon or Oxford suits daily use: the bags in our table hold 1.5 to 2.2 litres. For rainy commutes or tactical use, choose a heavier fabric announced with a water-repellent treatment.
