Self-Poofing Fabric Transforms From T-Shirt to Parka

A small team at Otherlab, which does all kinds of weird things, has been using ARPA-E funding to develop what they’re calling “thermally adaptive materials.” We’ll call it self-poofing fabric, for its ability to dynamically change its insulation in response to temperature. The idea is that the fabric will provide a small amount of insulation when it’s warm out, and then increase how insulating it is (by trapping more air) in response to colder temperatures. When you see the prototype fabric in action, it looks like magic.
