“What fabrics best insulate the body against the loss of heat? Tests demonstrate that an open-weave cotton fabric has the smallest insulation value. A dense cotton cloth gives somewhat more protection, and wool still more. But insulation value declines greatly when fabrics are damp; for wet cotton flannelette, the heat loss is greater than when the [skin] has no cover at all. The study suggests research for winter clothing: underclothing that will not readily absorb water, garments that will hold quantities of air in extremely small bubbles, and quilted clothes made of a batting of chicken feathers and cotton.”

It’s Time to Stand Up for Science
If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.
I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.
If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.
In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.
There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.
