Nylon and polyester ground sheets have a tendency to be lighter and much more packable, making them popular for backpacking.
Hydrostatic Head Rating
You'll often see ground sheets ranked by their hydrostatic head (HH) worth, gauged in millimetres. This number tells you how much water pressure the fabric can hold up against prior to it begins to leak. A score of 3,000 mm is generally considered sufficient for most camping circumstances, while anything over 5,000 mm supplies solid security in wet or prolonged-rain problems.
