This was super helpful on a recent 200 mile bike tour in Minnesota and Wisconsin. The temps were in the high 90s with high humidity and unrelenting sunshine. Several of us had these. We would open it, put ice cubes in it in a line, then roll it up and put it around our necks. It got me through this hideous heat while riding on more than one occasion. I now LOVE my cooling towel (and I bought one for my friends too).
