Groudsheet Polycro/window insulation film kit $5 at Walmart

That's the stuff and a great deal for that many square feet.

Are you guys sure it is the same stuff? And can you verify the weight of it (oz / sq yd)? If it's the same stuff, it's a great deal.

I'm curious where Gossamer Gear sources theirs.

I've read posts after posts "believing" that window film is the same as polycryro. Can anyone with experience with both materials vouch for this alleged sameness?

I have used both and they are both shrink film,they look,feel and last similarly to me.Here is what it says in the product description at Gossamer Gear.:Note: Since these sheets are made from shrink film they will shrink slightly when exposed to extreme heat. We tested these sheets in heat this summer and found that the sheets shrink 1" to 2" (3 to 5 cm.) in width and up to 5" (13 cm.) in length

I took advantage of this deal and was able to get the sliding door kit for $5. Awesome!

Like Anna, I can confirm that the window film looks, feels, and performs just like the GG groundsheet.

"I expect they are selling it off cheap because no sane person would be insulating their windows at this time of the year, which works out nicely for us insane backpackers."

If your home uses air conditioning as much as heating, then keeping the windows insulated in the summer cooling season is, technically speaking, the "sane" thing to do.

The problem is the inconvenience of removing the shrinkwrap in the shoulder seasons to open windows. Of course you have many square feet of perfectly usable ground cloths at your disposal!

I always wanted to lighten up from my tyvek ground sheet, but never wanted to pay for the shipping from gossamer gear. Thanks guys! Even if they don't last more than a couple trips $5 is a steal! I can make more than one too.

I got some window film off Amazon, $6 with shipping for a very large 120×84 sheet.

“If you get the outdoor rated window kit it wont shrink. The indoor version is made to shrink.”

But ‘outdoor’ is about 50% heavier and packs up bigger. The indoor stuff lasts long anyway. Just cut and plan accordingly for shrinkage. Or shrink it first and then cut.

Just found this at my local Walmart for $3! Hard to pass on it if even just to beta test!

Wow, they're giving it away. I'm gonna drape myself in this stuff.

5'x17' plastic sheet, can cut to (5) 3'x5' peices. It's .7 mil, and a total of 5.1 ounces, per the front of the box. That would be slightly over an ounce for each 3'x5' peice cut. And you get the double-sided tape, outlet foam seals, and some weather strip. They also had a $7 kit that was for (10) 3'x5' windows. Fairview (Troutdale) Walmart.

Glad to hear that people are taking advantage of these kits.

All you need is some gorilla tape and a hole punch (for stake eyelets) and you can make a poor man's cuben tarp which gives you a stunning view of the heavens at night (goldgear style). As an added bonus, you are much more likely to catch a glimpse of a bear traipsing its way past your tent at night. Not sure if I'd rather sleep in blissful ignorance with the world outside obscured by silnylon though. he he
