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
