Knowing the fabric we use…

Picking the right fabric is just as important as picking out the right bag. You want to get the fabric that will give you the best feel to touch. One that pleases you visually. Depending on your daily routine, you want a fabric that will perform to the challenges. If you travel by motorcycle or bicycle, you want a fabric that is durable and performs the best in various weather conditions. Would you prefer a lighter material or would you sacrifice for an aesthetically appealing fabric that is heavier? All that we will explore as we scope down on the two fabric available at Greenroom136.


Originally developed by DuPont in 1929 and is today a property of Invista; Cordura is a brand best known for fabric commonly used for consumer carry products, industrial and military performance apparel. It was a fabric designed to supersede poorer performing fabric such as cotton canvas. These fabrics are usually made of nylon but it’s been known that some do get blended with cotton and other natural fibres depending on the application. For more information about Cordura; visit their corporate website at or read it up on Wikipedia at

Specially designed to be tear resistant, light weight, highly durable, abrasive resistant and have better colour retention from fading.

With a high 1000 denier, these fabric will give a feel of confidence for longer lasting durability. Synthetic feel, soft and warm to touch. Rough surface; might cause scuffing on clothing.

Strong and in many bright, striking colours. Colours are harder to fade under typical circumstances. Every fold on the fabric will look natural with rare occasion of sagging; this is the result of the fabric’s rigidness. This rigidness also maintains the shape of the pack.

Colours won’t run when in contact with water. Because colours on Cordura are harder to fade, the colour on your pack will last longer and rarely will you experience the fabric patina with age. When fabric is new, you will experience water forming into droplets when in contact; this is the result of a weather proofing treatment on it’s surface. This treatment does tend to loose it’s effects after a long term use. To restore, some recommend a water repellent restoration spray such as Water proofing is by the help of a double layer polyurethane coating on the fabric’s underside. This treatment fills and clogs up fabric pores that would otherwise allow water particles to pass through of its surface and into the bag.

Surface of Cordura will not scuff due to abrasion. Sometimes a little scuffing might appear at sharp corners, commonly at corners found at the bottom of the bag; but we’ve not experienced much tearing in result of this.

Weather resistant
Water tend to penetrate through fabric via small micro pores found on the surface. All our Cordura supply are coated with layers of polyurethane which will fill and cover over these micro pores making it near impossible for water particles to pass through. But these coating will wear out after long extensive use. Sometimes we’ve seen polyurethane breaking up resulting in powdering or peeling; but since all Greenroom136 products are made with double ply of fabric, chances of seeing this occurring is minimal.

We did a little shear test with our 1000 denier Cordura, we managed to puncture the fabric with 15 kilogram of force. Watch the video for more details.

Care instructions
Clean your Cordura pack using a clean damp cloth. For dirt stains, some fans had reported using spray cleaners to varying success. Never machine wash as it will likely damage the integrity of the fabric which will affect it’s durability and ability to repel water. If you have a really filthy, dirt ridden pack, we recommend hosing it down with water. Sometimes a little soap and soft brush will go a long way. Never brush with stiff bristles. Never send your bag for dry cleaning. Avoid direct sunlight when drying.

Who is this for?
Active travellers, students, public transporters, bikers, heavy load users, and anyone needing a pack that is low maintenance but highly durable.

10.10oz Army duck

A 100% cotton based “Plain Weave” canvas fabric impregnated with Martexin® Original wax proprietary mixture. An American company with many years of experience in the field of wax coated fabric dating back to 1838. During the days of the frontier, farmers and cowboys would coat their canvas bags and tents with wax to make them weather and wind resistant. Eventually, industrialisation took over by incorporating liquid wax to treat canvas fabrics.

The fabric is expected to have a lifelong resistance to inclement weather, while cotton fibers allow it to breathe.  

Cool and soft to the touch like a good pair of jeans with a natural cotton appearance. Wax coating makes the fabric rigid and weather repellant. If you get a chance, try the hug test. Wax canvas is a heavier grade of fabric.

As it age, it will develop a well-worn and comfortable patina, enhancing the look of your Greenroom bag. The patina develops with long term use, and is in the same manner that leather ages and burnishes with time. This fabric is classy and will definitely stand out in a crowd.

Although the wax coating will repel off all sorts of weather; nevertheless the wax coating will wear out and making the bag vulnerable to weather conditions. Because all our products are made with two layers of fabric (one of outer and inner shell), if bad weather does go pass the outer shell, it’ll be unlikely that it’ll pass beyond another tough water repellant and tear resistant fabric; Oxford nylon. Some bags might even come with a third layer made of tarpaulin. After en extensive period of use, the colour will fade slowly.

This fabric is high maintenance but for it’s classy and vintage looks; one does tend to get carried away by it’s sheer beauty. Scuffing will happen if the bag is not well taken care; i.e. dragging on the floor, storing it near corrosive chemicals and etc. Because it is a soft fabric, the carrier will not encounter scuffing to their clothes.

Weather resistance
Good but this is not the fabric you want if you’re in the market for a tough and durable pack.

Softer fabric will puncture when encountering contents with sharp corners. Fabric will thin out from constant abrasion.

Available in limited colour options; mostly dull and darker than those found with Cordura. Will fade and discolour with use. This is one of wax canvas’ key selling point; the longer you use the pack, the discolouration and fade adds to the pack’s vintage aesthetics.

The wax coating on this fabric will wear off in time. Retouch your pack using heavy duty fabric wax compound such as the type made by Otter Wax;

Stains can sometimes be removed using a damp wet cloth. We recommend hosing down your army duck pack with water during those really filthy days. Soap will help but try to avoid using a brush. Never machine wash or dry clean. Avoid direct sunlight when drying.

Who is this for?
10.10oz Army Duck fabric is a clear winner for those looking for a vintage looking pack; one that will stand out from the rest. Due to the delicate characteristics of the fabric, it is recommended for less active individuals or to those that would manage their pack with great care.

To conclude…
So, in perspective. You pick Cordura for durability and functional to the use case. One would pick Army duck because it’s an amazing fabric to make a bag with. It’ll be the next best favourite outfit apart from your jeans.

The other deciding factor would be price; Cordura tend to be cheaper while wax canvas will cost and weight more because of the trouble needed to making this amazing fabric.
