This works great. It gets really cold and helps a lot in extreme heat. It is cheaper and lighter than others because it would work better if it was under a shirt or jacket. It is too cold to wear against the skin though. You need two zip ties or hose clamps for the low pressure tube. The vortex tube part falls off easily without anything holding the tube on the barbs. You have to change the Chinese quick connect for yours but it is glued on with red locktite or something similar. I had to put it in a vice. I was afraid of breaking it but it came loose. You could also make a leader hose with the supplied female quick connect. The belt to hold up the vortex tube barely fits my 34" waist. The vest is a little bigger and has some more room.
