Nylon and polyester ground sheets often tend to be lighter and much more packable, making them preferred for backpacking.
Hydrostatic Head Rating
You'll frequently see ground sheets rated by their hydrostatic head (HH) value, gauged in millimetres. This figure informs you just how much water stress the material can stand up to prior to it starts to leak. A ranking of 3,000 mm is generally taken into consideration enough for most camping circumstances, while anything over 5,000 mm offers strong security in damp or prolonged-rain problems. For ground sheets particularly, a greater score camping cots is always preferable, considering that they remain in straight contact with saturated dirt.
Sorts Of Waterproof Ground Sheets
