I bought the maximum of this product from their site and I was extremely disappointed by what I got. I would be very surprised indeed if there was any difference between the maximum and the minimum for this product.
It was thin and did not stop sweat from reaching my outer clothing. It worked as I hoped for about an hour and then it was all downhill from there.
It also what not what I would expect for having paid $12 each and then $10 shipping!
It helps contain the problem, but with a guarantee that it would work all day I am very disappointed and would not recommend this to anyone.
