AlphaCool 7V Circulatory Cooling Vest System

The ac in my car went out, so I decided to buy this. It works, however, I'm still trying to get used to it. The connectors freeze up so I can't use it first thing in the morning. After a couple hours, I am able to hook it up and it works. When I'm not driving, I put the entire thing in a freezer bag so it will stay as cool as possible. It's not like having ac in the car, but it does keep my core cool so I'm not sweating as much.

I have owned cooling towels, ice vests, phase change vests, a neck fan and an evaporative vest. This 7V circulatory system is in a completely different class than all of them. The continuous cold water circulation is what changes everything. The setup is simple enough that I had it running within 5 minutes of opening the box. Money well spent.

The 2.5L bladder pops out with a quick release for refilling. Takes about 30 seconds to swap in a fresh cold bladder if you have one pre-filled, or 2 minutes to refill and add ice from a cooler. That refill simplicity is what makes continuous all-day use practical. The engineering is clever and the operation reflects it.

Every other cooling vest I've owned cools for a period and then the cooling fades as the ice melts or the gel warms. This one circulates cold water continuously so the cooling doesn't fade — it's constant from the moment you turn it on until the bladder water warms. Add ice to the bladder and it stays cold for hours. Completely different experience from passive vests.

At $399 I expected a complicated setup process. It's actually straightforward — fill the bladder with cold water and ice, connect it, press the button and the pump starts circulating immediately. The whole thing takes about 3 minutes from box to wearing. I've recommended this vest to three people and the first thing they all say after trying it is how simple it is.
