Columbia announces Omni-Freeze ZERO, sports gear that cools you down the hotter you get (video)
Columbia is announcing the Omni-Freeze ZERO, a range of sports gear  that cools you the more you sweat. Blue rings of cooling polymer cover the garments, which swell when exposed to moisture -- letting air pass around you as if you had goosebumps. Unlike typical compression garments, which wick the sweat away from you, this puts your natural resources to good use, so much so that the company believes it's cooler than taking your top off entirely. The futuristic gear will also turn up in a new range of footwear, but before you can get too excited, there's a catch; it isn't due to hit stores until next year, so you've still got a few months of getting sweaty.

Если коротко, то в ткань подсаживают специальный полимер, который впитывает пот и разбухает, образуя пупырышки, таким образом, ткань приподнимается над кожей и позволяет воздуху циркулировать, охлаждая тело.
