Nylon and polyester ground sheets tend to be lighter and more packable, making them popular for backpacking.
Hydrostatic Head Rating
You'll often see ground sheets ranked by their hydrostatic head (HH) value, measured in millimetres. This number informs you just how much water pressure the material can endure before it starts to leakage. A ranking of 3,000 mm is typically considered sufficient for the majority of camping circumstances, while anything over 5,000 mm uses solid protection in wet or prolonged-rain problems. For ground sheets especially, a greater score is always better, given that they remain in direct contact with saturated soil.
