don't know where i read it but you can go on-line for "cooling bandana" there are neck,or headband or vest things which are activated by h2o someone told me to dry as much as possible in between for odor issues but febreeze also works well. i ordered 10 of them -neck and headband for myself and other family members who have to out in heat occ for work.i sure hope they work,i sweat like a *** even in cooler weather!!
