Wilderness clothing can be stylish but above all, needs to be durable and functional. In any wilderness setting, the place you actually live is inside your clothing. During the summer cotton works just fine. It will keep you cool, keep the bugs off, and give you protection from the sun. In any other season, fall, winter, or spring, you will want to seriously consider layers of clothing that do not include cotton.
Cotton soaks up your body’s moisture and holds it close to your skin which will cool you by evaporation. If it is chilly out, you do not want this cooling affect. For the rest of the seasons you should have three layers on.
There is a proper technique to using these layers. You don’t want to become overheated or you will sweat too much possibly causing hypothermia when the temperature drops. You may find yourself pulling off both the outer and middle layers then putting them back on again as the temperature and your activity demands. In any survival situation, maintaining the proper body temperature is critical.
Your wilderness clothing should include something to take very good care of your feet. This includes moisture wicking socks and the proper footwear. Whether it is cross trainers or hiking boots, you will want good support and protection from the elements for the appropriate season and terrain. Cross trainers may get you through the summer but in colder climates they just won’t do! A decent pair of hiking boots will cover the widest range of temperatures and conditions. In severe cold you will need arctic wear.
Think practical when choosing your wilderness clothing. The wild critters won't care what you are wearing.
