Looking for the lightest weight ground cloth you can find? The polycryo ground sheet is it. It is constructed from industrial grade cross-linked polyolefin. What this means is that it is extremely tough for it’s weight with amazing puncture resistance and economical to boot! These ground sheets are absolutely clear so you can see right through them to see if you missed any pebbles or pinecones after you set it down.
"I recently finished my 5-month PCT thru-hike using your Polycryo ground sheet under my sleeping pad and bivy. I was able to use the same one the ENTIRE 2663 miles, though it now has several duct tape patches on it. The next time someone asks you if it's durable, this is proof that it is. It definitely exceeded my expectations and at 1.5 oz (for the individual size), it is way light." - Wayne Herrick | Lakewood, CO
"A special mention should go to Gossamer Gear for their Polycryo ground cloth. The size medium ground cloths come in packs of two, and I was able to go with just one for the entire trail up to Washington, where I switched it out for the second in the pack. But the first one didn’t just do the PCT with me - it had also come with me for the entire New England Trail, two section hikes of the Appalachian Trail, and countless weekend hikes over the past three years. All told, it had about 3,500 miles of use before I retired it. For $8 per pair, and only approximately 1.5 ounces each, I will never need anything else for a three-season ground cloth."
