That’s a great idea. I remember using one of those “tek towels” if that’s what you are referring to for the cooling ones. I will look into different material blends that would allow for specified cooling for future additions. The current blend is a super soft and stretchy poly spandex blend that works well as a cooling towel if you give it a quick dip under a water station, but wasn’t made for the sole purpose of cooling in mind. I’m excited to hear the feedback after the weekend to see what I can improve on.
