The great things about a cotton bandana is that cotton is extremely absorbent. It can hold 27 times its weight in water.  You can use it to cool your skin and it feels great!<br> * If you wear cotton clothing while hiking and backpacking, the cotton will absorb sweat, but because the sweat is trapped in the article of clothing, it’s not going to be drawn away to create that cooling effect like it would be in synthetic or wool clothing.<br> * Bring some cotton along—on your hot trips—in the form of a cotton bandana<br> <br> Water<br> <br> * Humans are not camels.
