Here is is:

http://gossamergear.com/shelter....um.html

it weighs almost nothing and provides a moisture barrier between the ground and the bottom of your tent and it weighs almost nothing.

This is the one I use.  And the material is tough, too.


Tough enough for what it needs to do.

May be similar but not the same.  The polycryo sheets are lighter, pack smaller.  I have used both, the polycryo sheet is much better overall.

:) Where do you think Gossemer get's their "industrial grade cross-linked polyolefin" from?

It may not be Home Depot but it's someplace similar and there sure isn't enough difference in any of them to warrant a "best".

Choices are good.

Same stuff. I do have GG polycryo - same as the window film you get for the house.

I agree that the polycryo is the same stuff as the window film that you can get at Home Depot or, in my case, amazon.  BUT it's not the same as painter's plastic that HSF's Home Depot link goes to.

I tried to buy it from GG once but their shipping prices seemed really unreasonable.  Ended up getting it from amazon.  I agree it's nice and tough and super light, and it's probably fine under a tent, but as a groundsheet for a tarp (where you're sleeping directly on it), I found it too slippery and a pain to deal with.  It was like trying to spread out Saran Wrap.

Handy to have a piece to use as a make-shift tarp.

That's how it was for me.  I used it for a while, but then decided I would rather get holes in my floor.

GG is right here in Austin, so I can drive over to pick the stuff up. (So shipping isn't a problem, at least for me.) But my experience was that the stuff is tough, but hard to work with.

Mind you, it's very tough, and on at least one night during a horrendous rainstorm in a floorless shelter, it kept me afloat on enough water to make me feel like I was in a water bed - I stayed completely dry except for the usual "misting".

Tyvek is about twice as heavy as the plastic, but infinitely better.

I've tried all sorts of different products as groundsheets and have settled on the textured (sort of "pebbled") 2 mil painter's plastic, bought at the local hardware store.  I buy a roll and cut it to size.

It's a lot less slippery than the regular painters' plastic or the polycryo.  Also opaque, which I prefer, and doesn't stick to itself like saran wrap.  It's a little stiffer than the regular 2mil plastic, making it easier to create a make-shift "bathtub" in heavy rains.  And it's cheap.

I've used an old nylon pancho. It's mostly for protecting the tent floor. Cheap, light, plus, it's double duty. I've used it for almost 30 years.

Interesting.

I've been using Tyvek under tents for the last ten years and have found it remarkably waterproof and ideal for that application. However, I've never slept under it, though I have put miles of it on houses!

As an aside...

I know this isn't entirely "logical" as we all use disposable plastic in our daily lives. BUT, I find it more than a little "creepy" to use flimsy plastic as a backpacker knowing I'll wear it out and add another bit of plastic to yet another landfill.

Anthropologists say our generations will be known as "The Plastic People" in the future, with a foot of the stuff covering the planet. Yeah, The Graduate was spot-on.

So while my wife and I clean and re-use ziplock bags as well as recycle, I still throw plastic away so I'm absolutely not pointing fingers, just stating how using plastic as a ground cloth hits me.

Anyone else?

The shelter the OP will pair it with has a mesh floor.

At reasonable weights a film ground cloth needn't be any more "disposable" than a woven one. My Trailwise ground tarp from the sixties is completely devoid of waterproofing now. While my tube tent is still completely waterproof, from the same timeframe, though patched with numerous athletic tape bits.... Granted the tube tent has been relegated to tire chain application knee protection duty while I still use the Trailwise since it's more for dirt protection than water in the dry places i go.


Anyone not walking to the trailhead consumes vastly more petrochemicals than contained in an ounce of plastic sheeting as a suggestion....

I have both polycryo and tyvek groundsheets, I prefer the polycryo (from a window film kit) for weight savings. It can be a bit unruly in a breeze, but nothing that isn't easily handled by a few small rocks to weigh down the corners as I spread it out.

I get as much contractor's-grade garbage bag material as I want from my superintendent. It comes in a tube and I cut it. He uses it to bag the stuff from the garbage chute -- tough. Don't know the mils, but tough. It's heavy, but... Tough. I like it for where I go -- lotsa sharp rocks so it's gotta be tough. It's heavy, though. But heavy in a tough way.

Did I mention...?
