The article didn't seem to include much technical detail on how this works but I was hoping it would be closer to the Stanford research on effective body cooling[1] that was around 10 years ago and less just a vest holding frozen packs. From what I remember most traditional body cooling gel based vests have the problem of causing blood capillaries in the skin to close down. That stops the body from transporting warm blood from the core to the surface where sweat is used to cool it. To put it another way, they are too cold to really help with cooling. They idea behind the vacuum glove was that there are certain areas of the body with more capillaries and if you can keep blood flowing to them by not going too cold (say constant 12C) and by using a mild vacuum to draw blood to them you have a much better way to cool the body. I'm guessing that's much harder to work with than a simple vest holding gel packs. Seems a shame though that we don't have anything more effective right now. My own personal usecase would be better cooling than "loads of fans" when riding indoors on Zwift. The cooling vests I've tried so far weirdly just make you feel cold and hot at the same time. 1. https://news.stanford.edu/pr/2012/pr-cooling-glove-research-082912.html https://news.stanford.edu/pr/2012/pr-cooling-glove-research-...
