How to Dress for Hiking
The way you need to dress for hiking largely depends on the conditions you plan on hiking in. You need significantly less coverage for a quick hike in the heat of summer than you need for an extended hike in the middle of winter. Regardless of the specifics, however, you should wear clothes that wick away moisture from your skin while preventing precipitation from getting you wet. You should also dress in a base, insulating, and shell layer.
Insulating Layer

Dress in layers.
Layering is especially important for cold weather hiking. As you warm up, you can remove some of the layers to prevent yourself from overheating. When you need the extra warmth, you can put the layers back on.

Stick with short sleeves and shorts when hiking in hot weather.
Your skin needs to breath, and overheating can cause a variety of health problems. If an insect warning or other similar problem prevents you from exposing your skin, wear long sleeves and pants made of the most breathable, lightweight material you can find.

Look for garments that can keep you warm in cold weather.
Long sleeves and long pants are just the start. Vests, jackets, and tights are also important tools you can use to keep yourself warm.

Wear fabrics that wick away moisture while keeping you warm.
Polyester fleece is a popular option because it is lightweight and breathable. Merino wool and goose down are also common choices, but goose down must be kept dry to remain effective.
