The inspiration behind Zpacks’ comes from our obsession to carry the lightest weight gear in the world. Our gear must be more than just the lightest, it also has to provide total functionality while achieving those weights. To realize our goal, we have placed a focus on simple but innovative designs, manufacturing with cutting edge materials and constantly refining our processes. The search for the next generation of advanced technology will never end and neither will our desire to push the envelope for the benefit of adventurers everywhere. cuben cuben fiber
Waterproof Fabrics
Most Zpacks gear is made from "Dyneema® Composite Fabrics". Dyneema® Composite Fabric (Formerly Cuben Fiber) and features DSM’s bio-based Dyneema® fiber technology. Sourced from renewable, bio-based feedstock, it is the first ever bio-based ultra-high molecular weight polyethylene (HMPE) fiber. The fabric allows us to commit to sustainability while helping to reduce reliance on fossil fuel resources.
Dyneema® Composite Fabric 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. Dyneema® fiber has an extremely high tensile strength, and very low stretch making it ideal for our tents, tarps, and backpacks.
Dyneema® Composite Fabric is available in a variety of weights. All weights shown are waterproof.

This is the material used in our standard stuff sacks, and it is also the default weight for our 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. All colors are light and semi see-through.

Some care should be exercised to move pointy twigs, rocks, and thorns from your tent spot. Choose spots on dry leaves and soft needles when possible to prevent rain splash-up. Tape is included with the tent in case you get a puncture.
