Dyneema® Composite Fabrics (also known as DCF or, previously, cuben fiber) is simply the most technologically advanced performance fabric for the outdoor industry available on the market today for ultralight tents.

It is a family of high-end fabrics originally developed for the sailing industry. It is made up of crossing super-strong Dyneema® fibers (up to x15 times stronger than steel) laminated between two layers of Mylar. This construction gives DCF many advantages:

– It is extremely waterproof
– It has very high UV and chemical resistance
– The fabric does not stretch when wet
– It does not absorb water

The Challenge ULTRA™ line of fabrics is composed of the highest performing UHMWPE composite fabrics in the world.

In a class of its own, ULTRA™ represents a new paradigm in durability and weight. ULTRA™ weave is constructed with an optimal blend of UHMWPE & high-tenacity polyester. The tight weave is laminated with an eco-friendly adhesive to the revolutionary Challenge RUV™ film. The result is a textile that is incredible strong, lightweight, and waterproof to 20 000mm. ULTRA™ performs in the harshest environments, in both sub-zero and tropical climates.

Being such a lightweight material, DCF is a little transparent, however you can generally only see the silhouette of the person that is inside the tent and you will be unable to see the details. So feel free to change your clothes without worrying too much!

With direct and strong sunlight hitting your tent, visibility inside the tent might increase somehow.

DCF is the most tear resistant and durable fabric for its weight on the market today. That is why all our tents are made using various weights of DCF fabrics.

To know more about the specification of each fabric type, please visit our materials page.

ULTRA materials are not suitable for tents, as they are too heavy and thick for this application. For comparison, the DCF fabrics we use for tents are in the range of 18-25 grams per square meter. Mainstream silnylon tents on the market are mainly 40+ grams per square meter. The lightest pack fabric we use (DCF2.92) is 100 grams per square meter, and Ultra200 is 120 grams per square meter.

UHMWPE stands for Ultra High Molecular Weight Polyethilene

UHMWPE fibers (non-branded Dyneema® or Spectra®) are the lightest and strongest fibers commercially available, with a tensile strength 15x stronger than steel.  UHMWPE is created by a gel-spun extrusion process which draws out extremely long chains of polyethylene, aligned along a molecular backbone.  This alignment effectively transfers load through the fiber for high modulus and strength.

UHMWPE fibers are used in our DCF and ULTRA fabrics.

Our shelters are designed to reduce condensation as much as possible. Please keep in mind that environmental and weather condition play an important role in determining whether you will get condensation. Tents should usually be pitched far from water sources, other wet environments such as marshes and preferably not in low lying areas, if condensation is a concern.

Sometimes such environmental and weather conditions are beyond our control. In these cases, the best we can do is to maximize air circulation inside the tent.

In good weather with light rain and little wind, tent doors can be left open to promote air circulation. The tent can also be pitches higher than the suggested height to provide a gap around the perimeter at the bottom of the tent.

In stormy conditions ventilation opening on top of the tent can be left open. These are supported by a stiffener tube support to be sure that they resist high winds without closing. If desirable, vents can also be closed be removing the stiffening support from the velcro attatchment at its base. Please refer to the description of each product for more information.

Our tents are designed so that you can easily and quickly mount your tent in the field, a great advantage during bad weather conditions. To check how you can set it, please refer to the product page of the tent you are interested in or have purchased. You will find a link to the pitching instruction in the product specs.

Sure! Please send us an email specifying which component is missing or damaged, and we will do our best to help you out.

The Solus 1p and Duos 2p tent require a pole height of about 127-130cm. The Middus 1p and Middus 2p tents require 137-140cm.

A pole that can be regulated in the range 130-140cm will therefore work with both tents.

• Hang the tent to dry after each trip. 
• The tent should be kept in a dry place and not exposed to the sun and UV rays.
• The tent should be washed with a humid sponge and cold water at regular intervals to remove dirt. 
• Remember that one-sided DCF tape comes with the tent and can easily be used for quick but durable repairs. If possible, clean the fabric before applying the tape (regular alcohol wipes for cleaning are sufficient, if not extremely dirty). 
• Wrinkles and creases can weaken the material properties over time. It is recommended that you lay out the tent into a flat space, and then fold and roll it to a cylinder before packing it in the stuff sack.
• Always check that the zipper works optimally before each trip. Use zipper lubricant once or twice a year.

Measuring your torso length is an important step to insure you choose the correct backpack size.

We have published a video on our Youtube channel that shows how this is made.

Our tents, backpacks and accessories are made with laminated fabrics, so it is important to follow the correct steps in order to clean the gear.

• Use a soft sponge, with warm (not hot) water, in combination with a non-detergent and non-oil based soaps.
• Air dry the gear, by either pitching your tent or hanging the product.
• Do not use tumble dryer!
• Do not use concentrated heat like from a hair dryer to dry the products.

Yes, we do offer repair services on our products.

Please contact us so that we can discuss the type of repair that is needed.
