Waterproof Fabric


Most Zpacks gear is made from CTF Cuben Fiber Fabric. Cuben Fiber is constructed of a grid of white Dyneema threads laminated to a thin transparent polyester membrane. The Dyneema fiber is up to 15 times stronger than steel on a weight for weight basis. Dyneema floats on water and is extremely durable and resistant to moisture, UV light and chemicals.

Cuben Fiber has an extremely high tensile strength, and very low stretch making it ideal for our tents, tarps, and backpacks. It is unfortunately very expensive compared to other materials.

Cuben Fiber is available in a variety of weights. All weights shown are waterproof.

All fabrics are sold as a continuous length if you order multiple yards.

There will be a 20% Restocking Fee on any returned materials that we cut for you!

Ship on a Roll



Our fabrics are normally shipped folded up in a small package to keep postage costs to a minimum. If you need your material shipped on a roll (with no folds) please add an additional $10 shipping charge.

If you order multiple fabrics they will all be rolled on the same roll for one charge.

.34 oz/sqyd Cuben Fiber Fabric



This weight is very thin and does not take much to puncture.  It could be used for very light duty stuff sacks, or a tarp or tent if you are brave, or a vapor barrier. We use it for sleeping bag baffles and our Hexamid Pocket tarp (shown). Any seams on your projects will be the weak points- you may want to consider taping the seams.

Weight: .34 oz/sqyd (11.4 g/m)

Roll width: 54" (137 cm).

.51 oz/sqyd Cuben Fiber Fabric



This is the material used in in our Cuben Fiber stuff sacks, tarps, and tents. It has high tensile strength, but only moderate abrasion and puncture resistance due to the thin membrane material. Most of our products are sewn, then taped for strength.

Good for stuff sacks, tarps, and rain gear for those willing to be gentle with their gear. All colors are light and semi see-through.

.67 oz/sqyd Camoflage Cuben Fiber Fabric



This material is the same strength as .51 oz/sqyd except it has an additional layer with a camo pattern laminated in. It blends in to nature well. This material is also a bit darker and less transparent than usual Cuben and offers a little more privacy.

Weight: .67 oz/sqyd (22.7 g/m)

.74 oz/sqyd Cuben Fiber Fabric



This weight has a little bit higher Dyneema thread count than our standard .51 oz material above. It may be good in applications that require a bit more strength and abrasion resistance, like lightweight rain gear, or a bit more durable tarp for example.

Weight: .74 oz/sqyd (25.4 g/m)

1.0 oz/sqyd Cuben Fiber Fabric



This weight has a double thick polyester membrane which gives it better abrasion and puncture resistance. It is waterproof, and a good strength to weight ratio for cuben groundsheets, tent floors, or rain gear.

It is more of a charcoal gray, not quite as deep black as the photo.

1.43 oz/sqyd Cuben Fiber Fabric



This is a good material for ultralight backpacks and food bags. It has more than twice the Dyneema thread count of the thinner cuben materials, and a double thick polyester membrane as well. It has very high tensile strength (over 100lbs / inch), and excellent abrasion and puncture resistance.

Tip: The Dyneema threads in Cuben material are aligned vertically and horizontally, but not diagonally. Any pressure points on your gear (pocket corners, strap attachments, loops, etc) need to be reinforced with tape, otherwise the vertical and horizontal threads can pull apart.

Here is a Video that shows the relative tear strengths of 1.3 oz silicone impregnated nylon, .51 oz/sqyd cuben, and 1.43 oz/sqyd cuben fiber. Note that those two cuben weights were referred to as .6 oz and 1.5 oz in this older video.

2.92 oz/sqyd Cuben Hybrid



This material is made from the same 1.43 oz/sqyd Cuben Fiber as seen above on the inside, with a protective layer of 50 Denier Polyester on the outside. The outer layer gives it more strength, and abrasion resistance, prevents fraying, and gives it a nice solid color. This material is used on our Arc Blast Backpacks.

4.85 oz/sqyd 210 denier Gridstop Fabric



This popular backpack material is a little stronger against abrasion compared to Hybrid Cuben Fiber. It has a grid of white High Density Polyethylene (HDPE) threads for exceptional tear strength, as well as a diagonal woven ripstop. The fabric has a waterproof urethane coating on the inside.

This high quality fabric is manufactured in Japan. The finished weight of the fabric including the waterproof coating is 4.85 oz/sqyd (165 g/m). This product was formerly referred to as "Dyneema X Gridstop" however it is now made with equivalent HDPE fiber rather than branded Dyneema.

Our repair tape products will stick to the inside of this fabric.

1.85 oz/sqyd Tyvek



Tyvek material is very stiff and crinkly when it is new, but it softens up with use. Some people put it in their washing machine to soften it up.

Tyvek does not have any ripstop qualities so it is not the best choice for backpacks or tarps. It will also eventually pill and leak if it is continuously rubbed against, so it is not great for raingear which would rub against your backpack.

The one place Tyvek shines is it does not puncture easily and it is cheap, so it makes a good inexpensive replaceable groundsheet material. It is also good for prototyping DIY gear.

Weight: 1.85 oz/sqyd (62.7 g/m)

Roll width: 9 feet (2.74 meters)

Price: $3.50 per linear Foot.
