Polycro groundsheet from gossamer gear or tyvek from Zpacks are a couple options

Polycryo is the same material you find in window shrink film that's used for insulation. Get the indoor variety, it's lighter and is plenty strong. Amazon sells it if you can't find any at your local hardware store.

An option few think of is 1/8" EVAzote foam. Really good protection for the mat, light, plus it adds some insulation. Especially good with air mats.

Cheers

Yea, I would go with the polycryo. It's half the weight of the emergency blanket and at least as durable.

+2 to Roger, a great option - two pads weigh in at 350g (about 12oz) and will protect most 2 person tent floors. Weight is about the same as a cut to fit cheap blue tarp.

AMK SOL Emergency Blanket versus Polycro and Light Tyvek for strength + durability? on 07/14/2014 23:05:18 MDT Print View

Ken's option, the Adventure Medical Kits SOL Emergency Blanket (1-Person), is certainly lighter than Tyvek and probably just as light as Polycro, and those AMK blankets seem durable (have collected a few over the years). Can anyone comment on their durability versus Polycro indoor window film and lighter Tyvek kite material?

I think John Abela used one of the AMK sheets as a ground cloth.

I have one that I used as a groundsheet before buying a cuben fiber tub designed one from Zpacks. Works perfectly fine this way and is plenty durable for the job assuming standard care is used to police up rocks and twigs up before laying it down.

Ah ... what?
My grey 1/8" mats weigh about 80 g each.

The best stuff I've found for that application is the1025D Hard Structure grade Tyvek that was sold by Lawson Kline a couple of years ago. For me, it hits the sweet spot between weight, durability, puncture resistance, water resistance, and ease of folding. My 30" x 84" piece weighs 2.4 oz. If Lawson or another entrepreneur wanted to buy a roll and sell it here, I'm guessing it would sell well.

12oz for 2 pads on 07/15/2014 06:53:25 MDT Print View

Roger, I think he meant your regular pad plus the evazote.

Nearest Home Depot is 100+ miles away. Amazon delivers. Easy choice for me. Tyvek always reminds me of a building site and work, no thanks, I've found the durability to be acceptable. The black printing does come off fairly easily though. Slept sliding on snow and scraped most of the printing off.

I prefer Tyvek Kitemaking material. It's available on Amazon. It's a little bit more like cloth than the homewrap stuff, and is highly abrasion-resistant. When I'm not sure if I can trust a surface to my pad or tent or bivy, that's what I use. One and done.

The AMK blankets are polyethylene vs Mylar in other space blankets, making them quieter and far less prone rn to ripping. The window film kits are great and you can order a large one that will make 2-3 ground sheets for solo. Both materials are stretchy enough to handle the lumps and bumps without tearing.

You can order the lighter weight Tyvek from kite making suppliers. It is softer and quiter.

I use the window film.

Roger-

Mine are the thin yellow 'bivy' ones from MEC and are 5mm thick, so closer to 1/4". With your 1/8" thick ones two would be lighter than most commercially available tent footprints, nice!
