There's a few of these peltier coolers on the market already [1][2]. The theory is that since we are cooling using direct-skin-contact and utilizing blood-flow to cool the body it is much more efficient than air cooling.

First two look like marketing scams too, too small to do anything. You need good skin contact AND a way to prevent body from fighting the temp difference by drawing blood away from cold spot, aka Vacuum. https://news.stanford.edu/2012/08/29/cooling-glove-research-082912/ https://news.stanford.edu/2012/08/29/cooling-glove-research-... https://www.rtxcorecontrol.com.au/ https://www.rtxcorecontrol.com.au/ earlier prototype from 2007 https://www.wired.com/2007/05/corecontrol-rtx/ https://www.wired.com/2007/05/corecontrol-rtx/ I remember seeing this one on Discovery TV

  The cooling glove you linked seem to be aimed at cooling at a much more faster speed than just casually cooling off though, they mention Athletes, firefighters and soldiers. Embrlabs spun out of an MIT project called Wristify and have a patented wave-like cooling, which is supposed to prevent the body from going into cold-spot-prevention mode. There's a lot of reviews, including pictures, where the vast majority says it's working as advertised https://embrlabs.com/embr-wave/#yotpo-reviews https://embrlabs.com/embr-wave/#yotpo-reviews but under-powered for some users.

    Regarding the Embr, while I'm not actually insinuating foul play per se, I generally ignore reviews that appear on the manufacturer's own website, for obvious reasons. If anyone has first-hand experience with these devices, I'd love to hear it! There doesn't seem to be a ton of critic coverage, and what there was didn't really go over how well it works in detail. I'd readily buy one if I trusted that it could actually be effective.
