If you work outside this time of year, the heat can get unbearable, even dangerous in a short time. This Cooling Vest will help you to "keep your cool" while working outside.
Step 1: Step One: Find Someone Who Can Sew.....
First of all, I'd like to give credit where credit is due. My dear wife of 38+ years of marriage (6 of them happy) did all of the construction of this vest. I just came up with the idea.
The downside is that she comes up with all kinds of stuff for me to do outside now.
Step 2: The Cool Part...
The lining of CLEAN UNUSED adult diapers is, by design, highly absorbent and becomes a gel when "activated". If you take the lining from several diapers and a mixture of water and alcohol you can create a mixture that doesn't get rock hard, but is more like a slushy soft drink when frozen. The alcohol to water mix ratio is kind of up to you. You might want to experiment. We're trying 50/50, and 25(alcohol)/75 mixtures now.
Step 3: Preparing the Cooling Packs...
Scoop out some of the alcohol and water gel into standard size sandwich bags and place flat on a rack in the freezer for 24 hours. Double bag the sandwich bags (one up, one down) to prevent leakage.
Step 4: The Vest
We tried to find a fabric that was both breathable and somewhat water resistant so that the vest would cool me but not soak my clothes from condensation from the cool packs.
Step 5: Time to Get to Work.
The pockets on the vest are just the right size to slip the frozen cool packs into. A small Velcro patch keeps the flaps on the pockets closed and keeps the cool packs from falling out.
Step 6: Off to Work
My wife wanted to Velcro the front of the vest as well, but the pockets filled with cool packs made it a little too snug to wear that way. We used some nylon straps with plastic buckles left over from another project for the front closure.
I jokingly told her that I needed a cool pack for my hat too. It looks like that's going to be another Instructable.
Oh well, off to work.
