Explaining the science of fishnet clothingfrom @theironsnail

Transcript

Apparently, Norwegians wear fishnets under their clothes and have been for over a hundred years. So I wanted to figure out why are they doing that. In all seriousness though, fishnets are incredibly useful when worn under clothes. Just rank the first ever people that summoned Mount Everest. Decades ago though, they were incredibly popular. There's a ton of ads about them, just jolly folks wearing them, but they weren't called fishnets. Even though originally they were made out of fishnets, they were called health vests or string vests. The reason that everybody was such a big fan of string vests or health vests was because of an invisible layer of air trapped right here. When the mesh is uncovered, obviously, that area of air is moving about, nothing is staying still. It's basically like you're shirtless, which is really helpful if you're doing a big expedition and need to vent heat really fast. But when you put a layer over that mesh and cover up the holes, the mesh essentially is pushing that layer out just a tiny bit. It's not connecting with your skin. And since it's a mesh, as it's doing that, moisture, water vapor, and everything can pass through the holes easily and get stuck on this layer instead of that layer, keeping the moisture off of your body. That really helps regulate your overall body temperature and make you feel a lot more comfortable when you don't have wet, clammy clothes sticking to you at all times. And in a similar vein, that invisible pocket of air that I was talking about before gets trapped by the outer layer, which makes this really, really insulating in hot or cold environments. And according to Better, who did not sponsor this video, it makes their base layers four to six times warmer than one that wasn't mesh.
