Nylon and polyester ground sheets often tend to be lighter and extra packable, making them preferred for backpacking.
Hydrostatic Head Ranking
You'll commonly see ground sheets ranked by their hydrostatic head (HH) worth, determined in millimetres. This figure tells you just how much water stress the textile can stand up to prior to it starts to leak. A rating of 3,000 mm is usually taken into consideration enough for a lot of camping situations, while anything over 5,000 mm provides strong protection in damp or prolonged-rain problems. For ground sheets particularly, a higher score is always preferable, given that they remain in direct contact with saturated soil.
Types of Waterproof Ground Sheets

Sturdiness and Thickness
