thin to thick makes the most sense. It's hard to remove only the thick layer if it's in the inside.

That being said, I'm not 100% sure of this. There *might* be some added value of having the thinner layer closest to the skin, so as to prevent the air movement closest to the body.

I disagree with this assumption. there's a heat source on one side. -- nm - loosilu Jun 26, 15:02 5
- So? Heat retention and insulation still work the same. (nm) - musubi Jun 26, 15:03 4
  - what about convection? you would want the wind blocking layer on the outside. -- nm - loosilu Jun 26, 15:03 3
    - yeah, that's the important factor -- nm - zeitgeist Jun 26, 17:54
    - what wind blocking? you are changing the parameters. -- nm - zork Jun 26, 15:06
    - There is no difference if we're talking about blankets that you're lying under. The assumptions mafic made - musubi Jun 26, 15:06
