Using 1/8” Closed Cell Foam as a groundcloth?

Hey, I purchased some good 1/8" CCF about a week ago from OWF here in Idaho. They sell it and a couple other thicknesses as 2 pound density. It is a med grey color and very soft to the touch. I used a cut down piece in my hammock last weekend in the Sawtooths. They sell it in 40"X80" pieces — no idea what shipping would be on that but the hole role was probably not more than 10-12 OZ. I cut it down to 35"x65"-ish and weighed that at 7.5 OZ.

Here is the web address to their page– look all the way to the bottom product –"FY20"

Good luck

"Or heck, even 72 x 20 size? All I can seem to find is the Gossamer Gear pads, which are torso length."

If all else fails, order two GG 1/8" pads and duct tape them together.

Sounds like the Exped MultiMat – it is basically a thin closed cell pad that also has a finished nylon cover on one side. It is a little heavy at 19oz but at 80"x39" it is quite useful – we used it this past weekend as a picnic blanket and I got it to try out as the dog's sleeping pad. I could see it used as a ground cloth, it appears very versatile. So far I like it – it is a niche product but it looks like it has its place in my gear closet.

Excellent! I have wanted some CC foam in .25" and wide enough to cut custom-sized pads for under my Trest PLIV and my new Neoair, whenever it finally arrives here. The OWF stuff is EXACTLY what I want, thanks.

I pretty much always use a 1/8" pad.
You will also want to use the Poly ground cloth.

They are so much stronger than painters drop cloth.
The 20" wide pad just isn't wide enough to be able to keep the elements from getting all over you.

I've used but found it didn't hold up terribly well. Pine needles pierce it and if you don't or can't get every rock and stick cleared, those can make pretty sizable tears in it. Just my experience.

wouldn't it soak up a lot of water and/or moisture as the nights went on?

I believe they are talking about a closed cell foam, thus no water absorption.

They do absorb water, just not as much. Neoprene (wet suit material) is also closed cell.

Closed cell foam simply does not absorb water into the cells themselves, but still absorbs around them.

I used to bring a small/light groundsheet, but now I just use a padded sheet – a 1/8" CCF pad. While they may theoretically absorb water, I haven't noticed anything in the past 2 years or so. They get beat up a bit, but I'm on my 2nd one in 3 years which isn't too bad. I guess it depends on how much you use it. I originally used the GG thinlight, but ended up sourcing a full length version.
