Tents and Tarps

If you are on the road, you can easily repair the tent pole by using the included repair sleeve. On most of our tents you will find this as a spacer by the ventilation hoods. The only exceptions are the HL and UL tents. There you will find the repair sleeve with the other accessories in the pack sack.

To make the repair in the field, slide the sleeve over the broken section of the pole and tape it in place. When you return from your trip, you can bring the pole back for repair.

When you return from your trip, whether it's a weekend or several weeks, it's a good idea to put your tent up again in a dry place so it can dry out. Be sure to clean the interior, wipe off any dirt that has stuck to the underside, and clean all zippers with a damp, warm rag. If the tent has been used in dirty and/or sandy conditions, you can lightly spray it with water to loosen the dirt from the material, coating, seams and zippers.

How long you can use your tent depends on a variety of factors. UV radiation is the main enemy of all materials used outdoors. Ultralight fabrics made of synthetic fibers are particularly sensitive. The type of use, i.e. whether the tent is pitched daily for months, as on an expedition, for example, or whether the tent is only used for a short time each month, has a great influence on the behavior of the materials. For example, a tent may already show damage to the material after an expedition (it becomes brittle and may tear), but with normal use the tent will last for years.

The influence of UV radiation on the tent can be influenced. Place the tent so that it is not in full sun during the day.

Another enemy is dirt and sand. These promote the abrasion of coatings on the fabrics and sand down the zippers, so to speak. Important: After using the tent in a sandy environment, be sure to clean the tent and especially the zippers with water.

Moisture can also shorten the useful life of your tent. If a tent is stored with moisture between layers, mold will grow and degrade fabric and coating. In addition, mold can also leave an offensive odor, making the tent unusable.

All these reasons make it difficult to predict the life of your tent.

Although it cannot always be prevented, there are several ways to reduce or eliminate the formation of condensation.

1. reduce or remove as much wet equipment as possible from inside the tent.

2. ventilate the tent when conditions permit.

3. use the appropriate tent floor (footprint) to create a barrier against the cold, wet ground.

4. use a small sponge to wipe off condensation.

Unfortunately, condensation cannot be completely eliminated from a tent design. Cool air must flow into the tent and warm air must be able to escape. If this is not possible, condensation will form. Whenever possible, ventilate the tent, either by opening a vent in the top of the flysheet or leaving the flysheet open all night. The goal is to create a cross flow that ventilates the tent and removes the warm air.

To prevent your tent from getting moldy during storage, there is only 1 remedy. The tent must be 100% dry before you pack and store it. It is best to store the tent loose in a dry, warm environment.

Before storing a tent or a tarp, it is necessary to make sure that everything is completely dry. While a tarp dries relatively quickly, a tent may well take several days to dry. Storing a tent or tarp that is still wet can cause permanent damage to the coating. Store your tent and tarp accordingly in a dry place.

A tent should be kept as clean as possible. Remove dirt or bird droppings with water. Avoid detergents or mechanical cleaning, as these can damage the coating. Never clean a tent in a washing machine.

The footprint protects the tent floor from abrasion or damage through sharp objects.

Our 4-season tents are designed for optimal protection against wind and rain. This means that on one side the rainfly reaches the ground to protect the canopy from driving rain, wind and sand. The opposite side has a gap that allows free flow of air for venting. This also hinders high concentrations of carbon monoxide.

The floor requires a higher water column to cope with the pressure created by standing or kneeling on the fabric floor.

This is because a rainfly does not require the same water column a jacket may need to cope with the pressure created by backpack shoulder straps as an example. The waterproofness of a rainfly can be compared to an umbrella that is waterproof purely through the tension of the fabric.

A freestanding tent does not get its shape by tensioning it with various guy ropes, as is the case with tunnel tents. It stands already after pushing in the poles. However, this does not mean that it can or should be left standing straight. However, additional securing with cords and pegs is certainly recommended in most cases. The advantage of a self-standing tent is mainly an easier set-up for a single person or persons.

Dirty zippers wear out. As a result, they no longer close properly. To counteract this wear, it is important to clean them regularly. Especially if you are traveling in sandy or dusty areas. Good care products are available from McNett, such as Zip Care Zipper Cleaner & Lubricant. On the road, you can clean the zipper with a toothbrush and lubricate it with a bar of soap.

Resin stains on the outer tent are best removed with an ice cube or, better yet, a cold pack. On the inside of the stain, cool the area until the resin is hard and brittle, then carefully scrape off with a spoon. Any remaining stain on the fabric can be removed with Revivex Pro Cleaner from GearAid.

Our "extreme" outer tent fabric is made of nylon coated on both sides with silicone. The silicone coating makes the fabric extremely waterproof and does not reduce the tear resistance like other types of coating. At the same time, the silicone coating protects the fabric from UV radiation. Our 40D Nylon 6 fabric is completely waterproof and elastic. This makes it the first choice for expedition and 4S trekking category tents.

Advantages of extreme fabric:

- high tear resistance
- durability
- UV protection
- elasticity increases the tension of the outer tent and gives a stable tent in the wind

Disadvantages of extreme fabric:

- Fabric stretches because it absorbs water and therefore the tent must be re-stretched when wet
- silicone-coated fabric cannot be seam-welded

For what use do we recommend extreme tents:

- tours with a focus on durability
- expeditions
- tours lasting several weeks
- tours in exposed areas (high wind, bad weather, cold, snow)

The UL fabric is also made of nylon, but with 15D it is significantly lighter than the extreme fabric and is therefore used for very light tents. This fabric is coated with silicone on the outside to protect the nylon against UV radiation. On the inside, it is coated with polyurethane to provide high waterproofing, thus welding the seams from the inside with seam tape.

Advantages of UL fabric:

- optimal ratio of stability and weight
- Seam tapes welded for guaranteed waterproofness

Disadvantages UL fabric:

- not as durable as extreme fabric

For what use do we recommend extreme tents:

- tours with a focus on lightweight
- tours lasting several days

The minimum weight of your tarp includes the tarp and the guy ropes. The maximum weight also includes all the pegs, the pack sack and any accessories or repair kits that come with the tarp.

When you return from your trip, whether it is a weekend or several weeks, it is a good idea to set up your tarp again in a dry place so that it can dry out. If the tarp has been used in dirty and/or sandy conditions, you can spray it lightly with water to loosen the dirt from the material, coating and seams.

How long you can use your tarp depends on a variety of factors. UV radiation is the main enemy of all materials used outdoors. Ultra-light fabrics made of synthetic fibres are particularly sensitive. The type of use, i.e. whether the tarp is set up every day for months, for example, or whether the tarp is only used for a short time each month, has a great influence on the behaviour of the materials.

The influence of UV radiation on the tarp can be influenced. Position the tarp so that it is not in full sun during the day.

Moisture can also shorten the life of your tarp. If a tarp is stored with moisture between the layers, mould will grow and degrade the fabric and coating. Mould can also leave an offensive odour, making the tarp unusable.

All these reasons make it difficult to predict the life of your tarp.

There is only one way to prevent your tarp from getting mouldy during storage. The tarp must be 100% dry before you pack and store it. It is best to store the tarp loose in a dry, warm environment.

None of our tarp models require seam sealing to work well. Exped's "extreme" (siliconised) models' seams cannot be taped at the factory. These seams can be treated with seam sealer afterwards for safety. However, it is important to use the correct product. Be sure to follow the instructions for use to achieve a clean seal of the outer tent seams.

For all our "Extreme" tarps we recommend the use of McNett SeamGrip SIL, which has been specially developed for siliconised nylon fabrics.

For all other Exped tarps with PU coating, McNett SeamGrip TF is the right choice. These tarps are glued waterproof at the factory. So repairing a damaged seam is probably the only reason why this would be necessary.

A tarp should be kept as clean as possible. Remove dirt or bird droppings with water. Avoid detergents or mechanical cleaning as these can damage the coating. Never clean a tarp in the washing machine.

Tarps can behave like sails in windy conditions and high forces can act on the fabric, seams and cords in gusts. These can damage the tarp. Therefore, it is important to take the wind into account when setting up the tarp.

This is because a rainfly does not require the same water column a jacket may need to cope with the pressure created by backpack shoulder straps as an example. The waterproofness of a rainfly can be compared to an umbrella that is waterproof purely through the tension of the fabric.

Water column or hydrostatic pressure is a unit of measure used to describe the waterpoofness of fabrics. A 10 cm² fabric sample is tensioned under a water cylinder. The point under which droplets are pressed through the fabric indicates the water column.

Silicone coating is more expensive than PU coating and is mostly applied to polyamide (nylon) fabrics. The silicone coating increases the tear resistance and UV stability of the fabric. Silicone-coated fabrics behave dynamically when wet, which means that the tent has to be re-tensioned.

These fabrics cannot be seam-welded. To make the seam waterproof nevertheless, cotton coated polyester threads are used, which expand when they get wet. In addition, these seams can be post-treated with a special silicone seam sealer (SilNet).

A PU coating makes the tarp fabric waterproof. PU coatings remain flexible in cold temperatures and do not stretch when wet. PU coated rainfly seams can be factory seam taped for waterproof performance. PU coatings are less UV resistant than silicone coatings and can turn brittle with time. PU coatings are slightly heavier than silicone coatings.

Resin stains on the tarp are best removed with an ice cube or better with a cold pack. On the inside of the stain, cool the area until the resin is hard and brittle, then carefully scrape off with a spoon. Any remaining stain on the fabric can be removed with Revivex Pro Cleaner from GearAid.

The UL fabric is also made of nylon, but with 15 D it is significantly lighter than the extreme fabric and is therefore used for very light hammock tarps. This fabric is coated with silicone on the outside to protect the nylon. On the inside it is coated with polyurethane to ensure high waterproofness and thus the seams are welded from the inside with seam tape.

Advantages of UL fabric:

- optimum ratio of stability and weight
- Seam tapes welded for guaranteed waterproofness

Disadvantages of UL fabric:

- not as durable as the extreme material


For which use do we recommend UL Tarps:

- Tours with a focus on lightweight
- multi-day tours

Our Versa Tarps are made of heavier 70 D polyester coated with polyurethane on the inside.

Advantages of Versa Tarps:

- durable fabric
- less sensitive to UV radiation
- the tarp can also be used as a ground sheet

Disadvantages:

- heavier for the same area as extreme or UL
