I have to sterilize my hands about half a million times a day and was curious how it would affect the sport band. I cut the sport band into various pieces and applied different types of alcohol based sanitizers to them. Within just a few mins the germ x did this to the band. A cross section of the band makes it appear the band is made of two different materials so not sure how the "inner" material would hold up. Saved a piece of the band to do a heat test, ie hand dryers, later. Willing to test more of the same band to various products\conditions if anyone has requests.
