This item does its job. Keeps my core temperature down. I have worn it outdoors on my construction sites here in So Cal. The ice lasts about 2-3 hours depending on how hot it is outside. It's ice so you can't expect it to last all day, but I think 2-3 hours is great. – M. Carmona
This type works very well in dry Arizona and looks like a work vest. Easy to remove and freeze ice packs. – Bud
It kept me cold while working in a factory for over 3hrs and then i put it back in the freezer and it was still very cold when i took it off. So I still have no idea how long this will stay cold but it did its job!!! – J. Williams
I bought this vest in anticipation of doing some work on our property in 114 degree weather (Arizona). We had a bunch of fill dirt to move around in a Bobcat - everything was set up weeks in advance so I just had to grin and bear it. It's a pretty simple design and the level of adjustability (velcro, elastic cords) makes it perfectly functional. The thin layer of neoprene on the outside (blue) makes a good insulating layer to keep ambient heat from getting in to make sure most of the heat is sucked out of your body instead. The ice panels are easy to swap out and I found the vest pretty easy to adjust - perhaps because I read the directions and opened the little velcro compartments on the front that let out all the elastic cord so it can expand to size. I'm 6'2/210lb and it fits me just fine. On to the effectiveness - this vest is COLD. In that extreme heat I got about 2 hours before most of the vest was melted. I swapped ice packs in the deep freeze and got another 2 hours, but when those were toast the first packs were not re-frozen again. I'd estimate it probably takes 5-6 hours to freeze them so if you want to have cold continuously - you need 2 or 3 sets of ice panels. I plan to buy at least one more set. Although it's cold - it managed to make me mostly forget about the oppressive heat while I was working the Bobcat and I got hours of work done in conditions that would have otherwise probably made me sick. I was still sweating a little, but it made a big difference. A couple of times I had to get out to do stuff by hand like heft around rocks, etc. and it was not enough to keep up under those circumstances - but it was sure better than nothing. For anyone who lives in a hot area and does anything outside - this vest really helps. Away from the house - if you had a cooler and 2-3 extra packs I bet you could get 8 hours of dramatically increased comfort working outside. I'm looking forward to the other ways I can use this vest in the future - it's basically the equivalent of a great winter coat in a cold winter blizzard for those of us that have moved to warmer climes. – Nathan C.
I bought this for my fiance' who never excites over any gift no matter how much he likes it. He did on this! It is the best price too I have found for these. Ice panels freeze fast and last a good 3 hours at least that I know of. I bought extra panels to go with so he can switch them out as needed when he has to work in the boiler at the mill he works at. He loves it and it expands or tightens at the shoulders and at the bottom to fit any size man! That is awesome and he loves it . 2 thumbs up and then some! Shipping was faster than expected as well. – S. Womack
As anyone looking into cooling vests will know, they are sometimes expensive and not necessarily a fashion statement. This one, although it still has a utilitarian appearance, is quick, useful, portable and at present affordable. The panels come off and go back on easily for effortless use and fold quite conveniently, for a versatile, space saving fit into a freezer space. It also does a great job of keeping you cool! – Adomi21
The vest did the job of cooling. It lasts for about 2.5hrs in 110 degrees on a motorcycle if fully frozen. – Wlbrash
