·         Just soak your Cool Bandanna in cold water for about 15 minutes or so until it swells up about a half an inch spread evenly throughout the bandana and you are ready to keep cool for the rest of the day.   
DO NOT OVER SOAK.  It will keep expanding.

·         It will not soak your shirt or leave any residue.   

·         You can from time to time, re-soak it in some cold water just to get a refreshing feel, but it really does its work by using the evaporation cooling process to lower the temperature in your blood.  It’s the dampness that keeps you cool.

·         If you are out camping, at a sports event or any outside activities, in order to keep the crystals cooled off, we suggest:
A) Soak Bandana
B) Put in Zip Lock Bag ( allows the crystals to cool off, without soaking up the evaporation and over swelling)
C) Put in Cooler ( in the zip lock bag)
D) Allows you to keep your bandana colder without over soaking.

·         HANG UP AT NIGHT TO DRY OUT! 

Tips:   Feel like it isn’t cool?               Flip over the bandana to feel cool again.

              You'll know it's really working for you when you forget you've got it on, and all of a sudden, you realize that you're not hot and sweaty like you usually are at that point.  That's when you know it really works!

·         Re-use it over and over. 

·         To wash, just hang up to dry until it dissipates a little, and hand wash in regular detergent. 

·         Don’t wash in a washing machine.  It will keep on swelling and absorbing the soapy water.

Note:
Water from different sources will have different effects on the polymer.  Hard water with a lot of minerals and salts will not work as well as soft water. 
Distilled water is, obviously, the best, but if your water has a lot of minerals, try filtered water if you have it.
