Learning to Layer

Layering works, but you'll only be comfortable and safe from the elements if you make sure your extremities are protected from the damp and cold as well.

Use a hat: Body heat escapes through your head more readily than hands or feet. That's because it has a large, exposed surface area and a rich, warm blood supply that is not diminished when exposed to cold. A hat can therefore be one of the most effective dampers for quick adjustments in temperature. Put it on when you feel a chill, and take it off when you're hot and sweaty.

Get good gloves: Your body, when exposed to the cold, will limit the amount of blood pumped to extremities to preserve heat within the vital organs. That's why your hands and feet are the first things to get cold— they're being sacrificed, in a sense, for the more important body parts. Because body heat escapes easily through your hands, it's hard to keep them warm. If they get wet, you can more or less forget about it. Always wear a good pair of gloves that are breathable and waterproof.

Protect your feet: Like your hands, your feet can quickly get cold and allow heat to escape. In fact, your feet can pump a full cup of perspiration over the course of an active day. The best defense for the cold is to keep them dry and warm. Durably waterproof, breathable footwear will provide you with the insurance you need to enjoy your outdoor activity. Add to that a heavy pair of synthetic-fiber (such as polypropylene or polyester) socks and a thin pair of wicking socks, and your days of cold feet should well be over.
