Keep child comfortable by layering clothes

On all but hot, dry days, you and your children should wear multiple layers of clothing that provide various levels of protection against sweat, heat loss, wind and potentially rain. Layering works because the type of clothing you select for each stratum serves a different function, such as wicking moisture or shielding against wind. In addition, trapped air between each layer of clothing is warmed by the child’s body heat. Layers also can be added or taken off as needed.

Generally, both you and a child need three layers. Closest to your skin is the wicking layer, which pulls perspiration away from the body and into the next layer, where it evaporates.

Exertion from walking means you will sweat and generate heat, even if the weather is cold. The second layer is an insulation layer, which helps keep you warm. The last layer is a water-resistant shell that protects you from rain, wind, snow and sleet.

As the seasons and weather change, so does the type of clothing you select for each layer. The first layer ought to be a loose-fitting T-shirt in summer, but in winter and on other cold days you might opt for a long-sleeved moisture-wicking synthetic material, like polypropylene. During winter, the next layer probably also should cover the neck, which often is exposed to the elements. A turtleneck works fine, but preferably not one made of cotton, as this won’t wick moisture from the skin when you sweat. The third layer in winter, depending on the temperature, could be a wool sweater, a half-zippered long sleeved fleece jacket, or a fleece vest.

You might even add a fourth layer of a hooded parka with pockets, made of material that can block wind and resist water. Gloves or mittens as well as a hat also are necessary on cold days.
