Rated 5 out of 5 by from Beat the Heat! I bought this shirt (in every available color!) for outdoor workouts this summer. My very first long cycling excursion in this shirt was during 105 degree temperatures, and the shirt performed like a champ and kept me pretty comfortable. It's well worth the price!

Rated 5 out of 5 by from Only option for high humidity The only option for high heat / high humidity environments. When heat exhaustion/stroke is on the menu as a side dish to the main course of heavy physical labor, this omni-freeze technology is the only thing that works in a platform that allows for mobility. I have to wear a normal, slightly heavier cotton shirt at work for my uniform. the sleeveless version of this omni-freeze shirt works very well under it, concentrating its magic on your core without adding unneccesary fabric down the sleeves. the only garment in 'class' for mobility that i can find anywhere from anyone else is a combination of sweat wicking and evaporative cooling. once you go beyond evaporative (aside from this omni freeze technology) you are looking at ice vests, water cooled, belt air conditioner, or something phase change (which is as bulky as an ice vest and just as short lived) Technically speaking the omni-freeze can probably be classified as a phase change garment. It uses a method of impregnating the shirt with tiny shape changing objects smaller then you can see which alter their shape on contact with water and draw heat off you the exact same way evaporation does. evaporstion leeches heat from you the moment when water becomes water vapor the same way this shirt leeches heat when the shapes change shape on water contact. so to recharge the shirt after it is saturated means simply wearing it exposed for ten or 15 minutes in an environment with a draft and no direct moisture. it will still dry itself out even in high humidity because it is mostly a fine mesh type of construction - but if actual rain is landing on it then it will suck it in. (if i wear it as my only shirt and spend ten minutes in an air conditioned convenience store over lunch it is refreshed and ready to go) when it is really soaked you can wring it out good and be back to 80% or better function in just a few minutes. this shirt literally uses science to create a simulated process of sweat evaporation, just absent the need for sweat to be able to evaporate. before i found this shirt i spent three weeks being on the edge of heavy heat exhaustion/heat stroke daily at the end of my workday. after having found this shirt i barely touch heat exhaustion levels, and if so only until i stop actively doing whatever it is i am doing. a few minutes of not exerting myself and the omni freeze sleeveless shirt brings my core back down to safe levels. after using this shirt for a week, my supervisors and close co-workers all agree i am a completely different and fully functional person who is not compromised by the heat. Having hit stroke territory a few times over those three weeks, it is not a stretch to argue that this shirt is saving my life by keeping me from reaching those dangerous core temperature levels in southern florida, where the heat and humidity are both off the charts -especially for someone used to working in northern climates. Highly recommend, this technology is solid science and and the quality of the garment(s) is top notch. I have two of these shirts and two more are on the way. worth every penny if you have trouble keeping core temp down in high heat/humidty environments.

Rated 5 out of 5 by from Great Undershirt My husband wears this under his vest (he is a police officer) and he really appreciates the cooling technology especially during the warmer days. They wear very well. This version seems a bit lighter in weight than the previous versions. He will also wear them for workouts but the main function is under his uniform.
