No need to wait, you can have a bag with reflective layer today. (Scroll down to "radiant.") It'll cost ya.


Their you go.

The only thing is, he says they put the reflective layer on top of the down. I believe that the reflective layer would work better if it were placed 1/8"-1/4" above the inner layer (closer to your body), and with the down on top of the reflective layer to add R value.

The best solution might be to add a very thin inflatable layer made with a reflective surface inside the top layer of the bag. A NeoAir that's 1/8' thick if you will. That obviously has the "spring a leak" draw back, but it might work incredibly good too and it would inflate with just a puff of air.

I'm just a futzer at heart. The design, testing, and manufacturing processes interest me, but the business side doesn't a bit.
