Review: Life saver, let's me make it through the day in the summer heat - Very impressed, so far so good, with the florida heat these are definitely a life saver. With the bladder to the full line I personally find them a bit to heavy to be comfortable in our industry which involves going up and down ladders on roofs etc, but filled about 2/3rds of the way I find the weight better and more comfortable. So far very few complaints, as I type this Im wearing it it's about 95 degrees I started the day with a frozen bladder and I'm going on about 2 1/2 hours. We purchased one for everyone on my crew and everyone seems to like them. Personally im about 20lbs over weight so sometimes I just leave it unzipped in the front and it still cools me well.
Review: It Works But It Won't Perform Miracles - It works but it's not a perfect system. If I completely freeze the water pouch it'll last for about 3.5-4.5 hours. If I just use ice it'll barely last an hour. But if you freeze the pouch you need to run it under some water or it won't work for quite some time. I've found the best way to use it is only turning it on for a few seconds at a time rather than continuous. One the skin cools down you stop feeling the benefits from it as much till those areas warm again. I've also noticed it getting so cold it collects condensation and feels like it may be able to cause frost bite if you're too wreckless with it. It's also not perfect at keeping your whole body cool, but it will give periodic relief. As someone who works outside for hours on end, it does help, but it doesn't compete with just getting into the air conditioning. Plus it will cool you from standing in the heat, but it won't stop you from heating up from exercising or working. Like I tried using it not get as hot in Beat Saber, but it just doesn't cool the whole body enough for that. Would need a whole body suit for that.

### ⭐⭐⭐ Vest review ( for outside workers)
*by D***R on July 7, 2025*

It will keep your torso cool, but will not stop sweating. Good for working comfortable in the heat. I use it for construction work, I work outside all day. You will have to fill bladder around 3 times a day to keep vest running efficiently.
