How to Dress for Cold-Weather Walking. While some people still face wintry weather with a heavy wool coat, wool sweater, flannel underwear and thick wool socks, many don't like being so bundled up that they can barely move. Luckily for us, modern technology has given us high-tech textiles. We can be warm and dry and still have freedom of movement.
New fabrics insulate, block the wind and wick away moisture without bulk or heaviness.
Layers, layers, layers Layering your clothing is still the safest bet. That way you can adjust according to the weather and your activity level. Then you'll need an insulating layer for warmth. And last, you may need an outer shell to protect you from wind and rain. The shell should be water resistant, in some cases waterproof, and breathable.
