Materials used in ZPacks Gear

Most ZPacks gear is made from CTF Cuben Fiber Fabric. Cuben Fiber is constructed of a grid of white Spectra threads laminated to a thin transparent polyester membrane. The Spectra fiber is up to 15 times stronger than steel on a weight for weight basis. Spectra 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.

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

1.42 oz/sqyd Waterproof Breathable Cuben Fiber-eVent 
This is probably the lightest 3 layer wpb fabric in existence, perfect for your ultralight rain gear and other projects.

The fabric is a three layer laminate with high strength Spectra fibers sandwiched between waterproof breathable eVent membranes on both the inside and outside. The strength, waterproofness, and breathability have all proved to be very good. The abrasion resistance is decent, but it can show visible wear marks in high wear areas like under your pack straps or belt.

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/m)
Roll width: 54" (137 cm)
Price: $30 per HALF linear yard ($60 per linear yard)

1.62 oz/sqyd "Challenger" Waterproof Breathable Cuben Fiber-eVent


This fabric has a waterproof-breathable eVent membrane on the inside, Spectra threads in the center for high tear strength, and a thin layer of black Nylon on the outside for improved abrasion resistance and looks.

The strength, waterproofness, and breathability have all proved to be very good. Our jackets for example are breathable enough to sleep in or hike in (if it is cold out) without getting clammy.

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.

.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.

We currently have this in a very light Orange color, to distinguish it from our other fabrics. The color is shown on the tarp to the right.

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

.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. Not recommended for backpacks! All colors are light and semi see-through.

Weight: .51 oz/sqyd (17.4 g/m)

.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.

This is an option to upgrade any of our Plex tents to.

.74 oz/sqyd Cuben Fiber Fabric.
This weight has a little bit higher Spectra 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.

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/m)

1.43 oz/sqyd Cuben Fiber fabric.
This is the material used in our "Zero" 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 Spectra 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, or 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.

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.

Weight: 1.85 oz/sqyd (62.7 g/m)
Roll width: 9 feet (2.74 meters)
Price: $3 per linear Foot.

Cuben Fiber Tape
  (Single Sided)

This tape is adhered to  .51 oz/sqyd cuben fiber fabric as the backing material. It has a brown paper layer that peels away leaving clear adhesive stuck to a cuben fiber strip.

The 1" wide tape is great for strengthening, sealing, or repairing sewn seams on your stuff sacks, backpacks, and tarps. It can also be cut into smaller patches for punctures or tears.

It is sold in 54" length sections. Overlap the ends of the sections for longer length seams. One piece is enough for most stuff sacks.

Length: 54 Inches  (1.37 meters)
Width: 1 inch  (2.54 cm)
Weight: .12 oz per yard  (3.8 grams per meter)  /  .18 oz per 54 inches.
Price: $3.50 per 54" section.

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 with no backing.  The tape can be used to bond two layers of fabric with no sewing.

This sticks great to Cuben Fiber and some other materials. It will not stick to Silicone Nylon!

.7 oz/sqyd Ultralight Insect Netting.
This is the netting used in our Hexamid tents. Regular "No-see-um" bug netting weighs about 1 oz/sqyd. This ultralight version weighs roughly 30% less without noticeable difference in performance. It has extremely small holes which block even the smallest of insects including mosquitoes, noseeums, etc.

.75 oz Pertex GL Ripstop Nylon. NEW!
This is the lightest version of Pertex ripstop nylon available. It is a very high quality 10 denier fabric manufactured in Japan. It is almost indistinguishable from 20 denier Pertex Quantum, but 21% lighter! It is coated with durable water repellant (DWR). The finished weight of the fabric is .75 oz/sqyd. The inside of the material is slightly more shiny than the outside.

Unlike most other nylon fabrics in this weight range, Pertex has a ripstop grid of threads, making it stronger and more resistant to tearing.

This material has a soft feel. It is a good choice for wind-breaker jackets, quilts and sleeping bags. We use this on both the shell and the liner of our Sleeping Bags.

Pertex is available for Personal / DIY use only. Commercial users must go through official channels.

Weight: .75 oz/sqyd (25.4 g/m) - finished weight.

Zippers

#3 Non-Separating Continuous Coil Zipper Tape - NOT WATERPROOF
(Tent / One-way sleeping bag zipper)

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. Zipper sliders are not included. You would want to add one or more #3 sliders sold below.

Weight: .33 ounces per yard / 10.2 grams per meter
Price: $.40 per foot (30.5 cm) - Adjust the length in your shopping cart.


 

#3 Non-Separating Continuous Coil Uretek Zipper Tape - WATERPROOF
(Zipper for waterproof bags / pouches)

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. Zipper sliders are not included. You would want to add one or more #3 sliders sold below.

Weight: .42 ounces per yard / 13 grams per meter
Price: $1.45 per foot (30.5 cm) - Adjust the length in your shopping cart.


 

# 3 Double Pull Zipper Slider (for either waterproof or normal zipper tape above)

These sliders will fit both the normal and 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


 

#3 Separating Zippers for Jackets - NOT WATERPROOF

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.

Price: $8.95 each


 

40" #5 Two-Way Separating Zipper for Long Jackets - WATERPROOF

Price: $9.95 each


 

100" #5 Two-Way Separating Zipper for Sleeping Bags - NOT WATERPROOF

Velcro Tape Strips

Normal self-adhesive velcro has a habit of peeling off. These 1/2" velcro strips are sewn to 1" wide tape strips. Since the tape is wider than the velcro it makes these extremely difficult to peel off.

The strips have brown paper on the back that is peeled away to reveal the adhesive. Peel the center of the paper off first where it is sewn through.

Suggested uses:
-Use 2 pairs to stick one of our Pillow Dry bags to your sleeping pad.
-Use them to keep raingear or other items closed.

Sold as male-female pairs.

You might also consider stick on loops and elastic straps as an alternative to velcro.
