They are neat, you just soak them in water for 5 minutes
and they keep you cool for days. I use mine while playing
raquettball, no more sweating. I also gave some to my nieces
for when they play soccer, my parents for yard work. They all
liked them, thought they were the most unique gift they had
ever gotten.
