Wicking Layer --
Keeping Warm and Dry

The wicking layer of our backpacking clothes provides the basis of our protection against cold and wetness. This is likely the most important and versatile layer of our 3-step recipe for clothing.

This layer, like much of our wardrobe will consist of a man-made polymer material of polypropylene as our best choice. Polyester or natural silk can be used as an alternative. However once wet, silk dries very slowly and is therefore best reserved for sleep wear.

The purpose of this layer, as the name implies, is to wick moisture from perspiration away from the body. Because moisture is removed from next to the body, heat is retained much more efficiently.

Typical Contents of This Layer

This layer of my wardrobe for a 3-season hike includes one set of polypropylene long underwear, one short sleeve polypropylene shirt, 2 pair of polyester or nylon socks (easily and cheaply purchased in the men’s wear department) and one pair of silk long underwear. In early spring and late fall I also add a pair of silk glove liners to wear under my mittens.

I like to buy the short sleeve shirt larger than the long sleeve shirt so that I have the option of using it as an insulation layer too.

Silk Makes Soft Sleepwear

The soft, comfortable feel of silk against the skin at night can’t be beaten. I only use my silk for sleeping, even leaving it inside my bag when not in use. It takes up almost no space and stays warm and dry.

Reserving a set of clean clothes for sleeping helps to keep my bag clean and reduces wear and tear on the inside of my bag. If you prefer, polyester or polypropylene can be substituted for silk. Just remember that it is important to reserve a separate set just for sleeping.

Socks

The polyester or nylon socks help to wick moisture from sweat away from the feet, thereby reducing the risk of blister formation.

Blisters are more easily prevented than effectively treated on the trail. A painful blister can rob you of much of the pleasure of your hike. Taking especially good care of your feet should be a top priority. You will want to obtain well-fitting socks without bulky seams.

With our wicking layer in place, we can now look at our insulating layer.
