Ultralight Groundsheet Materials: A (Subjective) Comparison

Some people place the highest value on absolute waterproofness and therefore choose films like xfoil made from cross-linked Polycryo (Polycro), while others focus more on durability and opt for materials like Tyvek or Cuben Fiber (DCF). Yet others might look for a lightweight and compact groundsheet and are willing to inspect their campsite for potential hazards like thorns instead of choosing the most robust material.

This comparison table is intended as a rough guide and provides an overview of different groundsheet materials, including their weight classes, waterproofness, durability, and other important characteristics. It is important to note that the table cannot cover all possible variants or their specific properties. Especially with TPU- and PU-coated fabrics, actual properties can vary significantly depending on the thickness of the base material and the type of coating. The quality and performance of these materials can differ greatly depending on the manufacturer, batch, and other factors.

In principle, comparability is possible due to standardized tests such as DIN EN 344-1 / ASTM D882 for tensile strength, DIN EN ISO 13937-2 or ASTM D882 for tear strength, and DIN EN ISO 13938-2 for puncture resistance, among many others. These standards provide an objective basis for comparing material properties. However, such values are often not specified, and even when they are available, they can be affected by variations in the product, batch, or coating.

We understand that a simplified representation of complex topics like this can often evoke emotions. We therefore welcome constructive discussions and feedback in the comments, as we, both as manufacturers and hikers, are eager to learn and improve.

In summary, there is no universally perfect solution for everyone, and the choice of the right groundsheet should be based on individual needs and priorities. The table is meant to provide useful guidance, but the specific properties and quality of the materials can vary widely.
