This Cooling Vest is amazing for those of us who do not do well in extreme heat in the summer months in the Midwest or anywhere for that matter. I got this so I could work outside without absolutely melting. So far I can honestly say it does work. It kept me way cooler and I could actually get some yardwork done. The vest has 10 cooling packs and runs off of battery that is rechargeable.There are 3 different settings for you to choose from, blue light keeps the pump working, then there is the green light that pumps for half a minute then stops for 2 minutes, white light pumps for half a minute and stops for 3 minutes.Overall I am very pleased with this cooling vest, it appears to be well made but if there is one complaint it would be to design it with alittle more length to it. Price point, Im not sure its worth the asking price it is currently at though. Seems alittle steep but it does help to keep you cool and thats what counts especially if you are a person that overheats or cannot take the extreme heat.
