You will not waste your money on this. Works good
It is just like what you would pay a heck of a lot more on Polar Max site. This vest comes with a set of Polar Max ice packs. I thought wow for this price. I had to jump at it. I have MS and I need it to keep cool. The Polar Max ice packs that come with it will keep you cool for about 2 1/2 hours depending on conditions.  I am glad that I bought this instead of spending well over 300 dollars from Polar Max Website. This is great saved me so much money I can afford the phase change packs.
