The breathing layer is usually the layer of clothing that comes in contact with skin. Ideally, the breathing layer allows body moisture to escape and evaporate more quickly, thereby keeping the skin dry. Use polypropylene long underwear to wick moisture away from the skin. Avoid natural fibers such as cotton, because they tend to hold the moisture close to the skin, making you colder. The insulating layer creates dead-air space between the layers of clothing, thereby trapping warm body air and keeping it around the body.
Jackets There are several important factors to consider when choosing the proper jacket.
Machine-washable jackets retain their waterproofing better than those that require dry cleaning. Jackets with outer shells made of tightly woven nylon or polyester are less susceptible to tears than those that are all cotton or made of microfibers. Even if a material is waterproof, water can still get in through seams that are not sealed, so look for jackets with sealed seams. In addition, Thinsulate insulation is hypo-allergenic, odorless, breathable, durable and easily dried. Make sure your jacket isn't too tight.
