Nylon and polyester ground sheets often tend to be lighter and a lot more packable, making them preferred for backpacking.
Hydrostatic Head Rating
You'll frequently see ground sheets rated by their hydrostatic head (HH) worth, gauged in millimetres. This number tells you how much water stress the textile can stand up to before it starts to leak. A ranking of 3,000 mm is normally thought about adequate for most camping scenarios, while anything over 5,000 mm supplies solid protection in wet or prolonged-rain problems. For ground sheets particularly, a higher rating is constantly more effective, because they're in straight contact with saturated soil.
Types of Waterproof Ground Sheets

For base camping, weight is much less of an issue, so longevity ought to take top priority. For backpacking, search for sheets that roll or fold down little and weigh under tents sale 300g.
Longevity and Thickness
Determined in denier (D) for woven textiles or GSM (grams per square metre) for non-woven materials, thickness straight affects how well the sheet stands up to punctures. A greater denier or GSM means greater durability, though additionally more weight.
Caring for Your Ground Sheet
