Nylon and polyester ground sheets have a tendency to be lighter and more packable, making them prominent for backpacking.
Hydrostatic Head Score
You'll usually see ground sheets ranked by their hydrostatic head (HH) value, determined in millimetres. This number informs you how much water stress the material can hold up against prior to it starts to leak. A ranking of 3,000 mm is typically considered enough for a lot of camping situations, while anything over 5,000 mm supplies solid protection in damp or prolonged-rain problems. For ground sheets specifically, a higher score is constantly more effective, considering that they remain in direct contact with saturated soil.

Weight and Packability
For base outdoor camping, weight is much less of a worry, so toughness must take concern. For backpacking, try to find sheets that roll or fold up down small and weigh under 300g.
Longevity and Density
Measured in denier (D) for woven textiles or GSM (grams per square metre) for non-woven products, thickness straight affects exactly how well the sheet resists leaks. A greater denier or GSM suggests greater durability, though additionally more weight.
Taking care of Your Ground Sheet
