Mid layers

The primary use of mid layers is to provide warmth to the body. Often, mid layers are made of a thin or medium thickness fleece material, but can also be a soft lambs wool sweater or knitted jacket. The layering principle, consisting of a base layer, mid layer and shell garment, creates air pockets that insulate, as well as transport moisture away from the body. If you become too warm, simply put one of these garments into your backpack to stay flexible and comfortable.
