This is better than down.

Down socks with soles of this stuff would be hard to beat! Boots made of this would be very welcome too.

Per the data sheet, .15gm per cc (I'm assuming that's the 9mm thick stuff). If my math is in the ballpark thats 1254 g (42.4 oz) per square yd. Halve that for the 5mm version and ends up around 21oz sq yd.

Thickness to thickness, with an R value of 10 per inch, a 9mm or .35" spaceloft pad would have a R value of ~3.5. In comparison, a 3/8" or 9.5mm thinlight has an R value of ~ 1.42 . For an R value comparison, a RidgeRest Solar (.75 in) has an R value of ~3.5 .

CCF R values taken from http://www.tenpoundbackpack.com/gear...sleeping-pads/

Of course R values are subjective, draw your own conclusions.

a spreadsheet for calculating weight and R value for a given sheet size. I can make it for any of these aerogel materials if we can get weight and R value info.

I just ordered a Shiver Shield jacket. I'll know soon enough whether it insulates like they claim it does. If the jacket works well enough, I'll order the pants also. I'm stil thinking of deep winter hammocking wearing this stuff and only using a thin top blanket and maybe a weathershield underneath. I'd still need to cover hands, feet, neck and head.

That's essentially what I use - down booties from REI or Lands End or such (I don't remember where they came from - a present, I think) + "Toasty Feet" aerogel insoles. In very cold weather I sleep in them, but usually need to take them off after an hour or two when my hammock tent warms up. I also use Toasty Feet insoles (a different set) in my winter boots.

I use Toasty Feet also thanks to WV.

Have you worn the jacket yet? I'm looking forward to hearing your review.

Me too! I'm a biker and look forward to the day they put aerogel into motorbike gloves.

More importantly though.... is it a step forward for winter hanging?

So how it works?

Btw, I've written to Shiver Shield and they answered that they will have by this fall: small sizes, insoles, stadium seats, hand muffs, and sleeping mats. Gloves and other accessories are in the works too, but not sure they will be available this fall.

As a hunter, this interests me, but the major thing I see is missing is, its not breathable.... so your natural persperation can't escape, who cares if its water proof, if you move around in it at all you will get wet, or am I missing something?

Would be nice for riding ATV out ice fishing or putting on after on stand.
