My current sleeping bag for expeditions to the Yukon territories weighs nearly 5 pounds. As I am always looking for ways to shed weight in my pack but practically need the -40 temperature ratings, I would like to know if anyone manufactures aerogel sleeping bags. I have been searching for days recently but nothing has come up. Thanks!

Given as I understand the stuff it's rigid I'd expect not. Without compression that'd be a huge package.

Every few years or so someone comes out with another product using aerogel.
soon after it disappears again from the market.
I have seen jackets and mats that I can remember.
Mostly I think it has to do with being brittle, something that does not work for backpacking.
BTW, as a dedicated party pooper, I usually point out that AeroGel was invented in 1931 so it has had enough time to mature.

From what I know in my studies of Aerogel, it is used in layers without contact to skin (apparently akin to Arsenic). It must be sandwiched. I know it is used in outer clothing layers for volcanic studies. I doubt very much that it will be used in such large quantities like what would be needed for a sleeping bag as the pricing is extremely steep. You'd probably have to go custom if at all. As mentioned, the only thing that I've seen it "stick" in the market is for insoles and that probably due to the minimal volume needs.

Camelbak makes a water bottle insulated with the stuff.
