We have a chest freezer so it's no trouble to keep them chilled and ready.If you are a carpenter, roofer, even a gardener, do not hesitate to get one of these. Yes, it is very expensive.But it can literally save your life. Priceless.
We bought this for one of our welders. They use it all summer with the heat, increases man hours because they aren't having to stop so much to cool down.
This product is saving my husband's life. He's a fence contractor in the Southeast and summer is a killer. Every year he dreads it. He's susceptible to sunstroke and heatstroke. With this on and a shade cloth to stand under he is able to go all day even in the punishing heat of July and August. Heatstroke can sneak up on you and the effects can be quite debilitating.You'll want to purchase another chill pack to go inside.
I got this because I have Multiple Sclerosis. These particular units are very bulky for me and don't go down low enough on my body. Also people ask me if I'm wearing a bullet proof vest, which is a little unnerving.The vest keeps me cool in this hot Virginia summer but due to the reasons stated above I can't wear it as much as I would like to.
