"In the mountains, sturdy, waterproof hiking boots are a must," instructs Auch.
The "must-have" list also includes:
Two pairs of socks—a lightweight liner (eg, polypropylene or polyester) and a cushioning sock made out of wool, plus warm (waterproof) gloves.
Mountain weather is generally cooler, cloudier, and windier than the climate in lowland areas, making improper dressing a serious health risk. Layering helps you stay cool when active and warm when at rest. Just add and remove clothes as needed.
Inner layer —Wear close-fitting long underwear made from polypropylene or silk, which should dry quickly and pull perspiration away from your skin.
Middle layer—This layer should be light-weight and breathable—flannel, wool, down, or fleece. You may want extra middle layers in colder climates.
Outside layer—To block wind and rain, try Supplex (wind-resistant) or Gore-Tex (great for rain and snow).
