Nylon and polyester ground sheets tend to be lighter and more packable, making them prominent for backpacking.
Hydrostatic Head Ranking
You'll usually see ground sheets rated by their hydrostatic head (HH) worth, measured in millimetres. This number informs you how much water stress the fabric can withstand prior to it begins to leak. A ranking of 3,000 mm is typically taken into consideration enough for a lot of camping situations, while anything over 5,000 mm provides solid security in damp or prolonged-rain problems. For ground sheets specifically, a higher score is always better, considering that they remain in direct contact with saturated dirt.
Types of Waterproof Ground Sheets
