Cotton for summer

We preach synthetic clothing for cold weather outdoor activities.  Synthetics repel water, including sweat, pulling it off your skin and pushing it to the outside layers of clothing.  Cotton, on the other hand, holds water against your skin.  In cold weather that translates to a cold body. 

But when it’s hot, cotton works well to keep you cool for the very same reason.  Drying is the process of a substance changing from a liquid to a gas.  When that is happening heat calories are used up from the nearest source--in this case your skin. 

As your sweat dries off your cotton clothes, you stay a cooler and happier camper.  Plus, synthetics, for some reason, become ripe with body odor in a much shorter time!
