Cross-Country Tech Talk by Stein, Eric's Son

Clothes: The Base Layer

There is no longer any need to be uncomfortable when cross-country skiing. Modern fabrics and clothing designs make it possible to stay warm and dry under conditions that would have been daunting to the most intrepid arctic explorer of a century ago.

Begin at the skin. Polypropylene remains the best material for a first layer. No other material possesses its wicking power, which is what keeps you feeling dry. New generation polypropylene products even overcome its only drawbacks, a somewhat rough feel and the tendency to retain odor. My favorite first layer consists of a longsleeve crewneck top ($35) and bike brief ($26.95) made of fishnet polypropylene. These garments are marketed under the name of Super Brynje (sic) by Reliable Racing Supply, Inc. (800-223-4448 or <http://www.reliableracing.com>). The fishnet design keeps the layer into which moisture is wicked away from your body (so you feel drier), yet it still does a good job of picking up moisture from your skin. The bike brief has a solid panel in the front that guys will appreciate on cold days. Sports bras for women that are constructed from similar materials with good moisture transport properties are also available. (Sorry, no experience with these, other than removing them in the dark).

With all these garments, as soon as you are done skiing, hug and rub yourself all over for a minute or so to allow the fabric to mop up any moisture that has accumulated on your skin. If you follow this plan you will feel dry within 10-15 minutes, no matter how wet you were when you stopped skiing.

The agony of the de feet. The other locations where the fabric next to your skin are key are your feet. Keeping your feet dry is not as big a problem as it used to be because of the improvements in boot design. Many boots now come with elastic cuffs that help seal out snow. Nevertheless, it still pays to take precautions, because nothing can spoil your skiing faster than cold, wet feet.

My preferred solution to this problem is neoprene socks ($20-25). These may be worn with or without liners (made of thin polypropylene). The neoprene provides a waterproof barrier, insulation and a cushioning effect that can prevent blisters. (I wear them in my downhill boots to prevent chafing) The only disadvantage to them is that your feet may feel a bit damp, but at least it's a warm damp. The dampness problem can usually be alleviated by the use of liners and/or some body powder. Neoprene socks are locally available. I've seen them for sale at Boyne Country Sports (Bavarian Village). If you buy some, make sure to orient the seams of the sock on your foot in such a way that the seams will not cause blisters.

One last word, unless you like hypothermia, avoid cotton all costs. Silk and wool are better, but will still leave you feeling damp for hours. This type of claminess is especially uncomfortable if you are sitting in the car for a couple of hours driving home.
