They are too tiny.
I have the car-cleaning PVA absorbent cloths and while they seem to be almost the same material, they don’t get and STAY cool the way the cooling material does, and they feel more rubbery.
I’m seeing lots of different brands, and that’s another reason I want to find out about this particular PVA stuff: it appears there may be knock offs that do not work the same way.
I also need to try pushing these a little harder to test how the cooling sustains, and I’m just the gal to pressure test them: A few years ago when I was a YMCA member I used the kind of cooling bandanas that are filled with the gel beads that swell when wet. I would soak them until swollen, and then freeze til solid. I would not only wrap my neck and head with solid ice, I would frozen bandanas into my bra, my pants, anywhere I could. Because the most miserable aspect of exercise for me is becoming hot. I really hate it and would love to be able to to build my own private gym inside a walk-in freezer. Perfect!
What was solid ice at the start of my 30-45 minute workout would be completely melted and unpleasantly warm by the end, so there wasn’t even a good way to “restart” them for the weightlifting, they were done until I could freeze them again, while this material becomes cool again the minute you wet it, and that’s an enormous advantage.
