Hey, have you heard all those "factoids" floating around about how you lose 40 percent to 50 percent of your body heat through your head? That's pretty close to true if you're submerged in the water -- but it's not the case when you're on dry land.
That doesn't mean you should leave your hat behind. A hat's great for keeping you warm in frigid winter or spring temperatures, or shading your head and neck in hot weather. It just means you should layer up your other body parts in cold weather too. As long as you're wearing layers, you can take them on and off at need to regulate your body temperature in accordance with how hard you're hiking (or how long you're resting).
