The Base Layer is the first layer of clothing you put on and it is in direct contact with your skin. For Outdoor Activities, it is very likely that you will be sweating, cooling down, sweating, cooling down, etc. It is important that your clothing works in a way that it can cool down quickly but not too much. This is where the base layer comes in.

The middle layer of clothingshould be a looser fit than the inner layer, but not baggy. It needs to maintain contact with the inner layer to function properly. These materials are designed to trap and hold your body heat in small air spaces in the material; hence, why mid layers can feel lofty. Mids are also designed to carry moisture away from the inner layer, moving it from the body and pushing it to the outer layer. Mid layer materials range significantly, but some common ones are fleece, polyester, down, and wool. Many manufactures produce patented synthetic and natural blended materials for mid weight layers as well.

Mid layers are not universally categorized in lights, mids or heavyweights, but you may see these terms occasionally used by some companies to describe the degrees of insulation their clothes provide. Depending on the temperatures you are in, you may need to wear more than one mid layer. For example, in cold conditions you may have a wool top and then a fleece jacket as well. That's the benefit of dressing in layers; you can add or remove clothing as you need to keep comfortable.
