Materials used in ZPacks Gear

Most ZPacks gear is made from CTF³ Cuben Fiber Fabric. Cuben Fiber is constructed of a grid of white Dyneema® (or spectra) threads laminated to a thin transparent polyester membrane. The Dyneema® fiber is up to 15 times stronger than steel and up to 40% stronger than aramid fibers 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. Buy Cuben Fiber Fabric. Buy Cuben Fiber Material.
 
 

1.42 oz/sqyd Waterproof Breathable Cuben Fiber Fabric
New! Finally waterproof breathable cuben fiber is here! This is probably the lightest 3 layer wpb fabric in existence, perfect for your ultralight jackets, bivies and other projects.

The fabric is a three layer laminate with high strength Dyneema fibers in the middle. In our testing the strength, waterproofness, and breathability have all proved to be pretty good. Our jackets for example are breathable enough to sleep in or hike in (if it is cold out) without getting clammy. The fabric is shiny on one side, and matte on the other. Either side can be inside or outside.

Due to the high cost of this fabric it is sold in half yard increments. One half yard would get you a piece 18" by 54". A typical jacket might take about 2 linear yards. Scroll down the page for waterproof zippers.

Weight: 1.42 oz/sqyd (48.3 g/m²)
Roll width: 54" (137 cm)
Price: $30 per HALF linear yard ($60 per linear yard)

.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. Any seams on your projects will be the weak points- you may want to consider tape or glue instead of sewing. Double sided tape is available below.

Weight: .34 oz/sqyd (11.4 g/m²)
Roll width: 54" (137 cm)
Price: $25 per linear yard.

.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. We use a specially designed triple stitched seam on our products which can be sealed with a silicone based sealer like Sil Net.

Good for stuff sacks, tarps, and rain gear for those willing to be gentle with their gear. Not recommended for backpacks! All colors are light and semi see-through.

** This product was previously listed as .6 oz/sqyd.

Weight: .51 oz/sqyd (17.4 g/m²)

.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/m²)
Roll width: 54" (137 cm)
Price: $27 per linear yard.

1.0 oz/sqyd Cuben Fiber fabric.
This material and each of the heavier weights have 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.

Weight: 1.0 oz/sqyd (34 g/m²)
Roll width: 54" (137 cm)
Price: $28 per linear yard.

1.43 oz/sqyd Cuben Fiber fabric.
This is the material used in the "Blast" backpacks. It has more than twice the spectra 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 diagonally aligned material 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 previously referred to as .6 oz and 1.5 oz in the video.

2.92 oz/sqyd Hybrid Cuben Fiber - Nylon Fabric
New! This material has tough 1.43 oz/sqyd Cuben Fiber (the same as seen above) on the inside, with a protective layer of nylon on the outside. The nylon gives it more strength, and abrasion resistance, prevents fraying, and gives it a nice solid color. This material is used on our Exo backpacks.

Disclaimer- The black nylon is not 100% color fast, it rubs off slightly on white clothing. The tan color doesn't have an issue. Plan accordingly; either wear darker clothing or use tan in contact areas.

Weight: 2.92 oz/sqyd (82.8 g/m²)

Cuben Fiber Tape
  (Double Sided)

This double sided tape works great for bonding two layers of cuben fiber material. This tape has high sheer strength, but lower peel strength so plan accordingly.

The brown paper layer peels away leaving just clear adhesive.  The tape can be used to bond two layers of fabric with no sewing.

Roll Size: 60 yards
Width: 1/2 inch
Color: Clear

Cuben Fiber Tape
  (Single Sided)

The 1" wide tape is great for strengthening, sealing, or repairing sewn seams on your stuff sacks, backpacks, and tarps.

Zippers

#3 Separating Zippers - Multiple lengths available

These are the type of zippers you would use on a non-waterproof jacket. The slider is included and it has a single pull tab accessible from the outside. These come apart at the bottom, unlike a continuous coil zipper below. They can be trimmed down to any shorter length.

32" length is about right for a typical jacket. 56" could be used for a long jacket or sleeping bag.

Weight: about .11 ounces / 3.1 grams per foot, plus .06 ounces (1.7 grams) for the included slider.
Price: $2.95 each

31" #3 Waterproof Separating Zipper

These zippers have a shiny waterproof coating on the outside. We use them on our waterproof jackets. They include a single slider which is accessible from the outside and they come apart at the bottom. They can be trimmed down to any shorter length.

These are #3 size (the smallest / lightest size available). They were special ordered from Japan, you probably won't find this size separating zipper anywhere else online with a waterproof coating!

Weight: .45 ounces / 12.8 grams each
(about .14 ounces / 4 grams per foot plus about .06 oz / 1.7 grams for the included slider)
Price: $8.95 each


 

#3 Continuous Coil Zipper Tape

This zipper tape comes on a big spool and is sold by the foot. This type of zipper does not separate at the bottom, and would be used for applications like sleeping bags, tent doorways, etc where at least one end of the zipper is sewn shut.

Sliders are sold separately below.

Weight: .11 ounces / 3.1 grams per foot
Price: $.40 per foot  (adjust the length in your shopping cart)


 

#3 Continuous Coil Waterproof Zipper Tape

This is the same as above, except with a shiny waterproof coating on one side. It is useful for applications like armpit zippers, or for waterproof bags like our belt pouches or multi-pack.

Sliders are sold separately below.

Weight: .14 ounces / 4 grams per foot
Price: $1.45 per foot  (adjust the length in your shopping cart)


 

# 3 Double Pull Zipper Slider

These sliders will fit either the normal, or waterproof #3 continuous coil zippers shown above. They have a pull tab on both sides, so they can be accessed from the inside or outside of your gear (for example on a tent doorway or a sleeping bag).

To install these on to the zipper tape, insert both sides of the tape part way into the slider, and then "push" the slider on to the tape with your index finger. It is tricky at first but easy when you get the hang of it! Pay attention to which way the groove on the side of the slider is facing relative to the zipper tape. They can be inserted on to either end of the zipper tape.

Weight: .08 ounces / 2.3 grams each
Price: $.35 each


 

#3 Single Pull Zipper Slider (for waterproof zipper tape above)

These sliders have a single pull tab which would be on the shiny side of the waterproof zipper tape above. You will want the shiny side facing out on your project. Use these when you only need to access the zipper from the outside (for example our our belt pouches or multi-pack).

Weight: .06 ounces / 12.8 grams each
Price: $.35 each
