Merino Wool Base Layer Shirt
The base layer is the most important piece of clothing for what to wear hiking. A good merino wool shirt like the Smartwool Merino 150 wicks sweat away from your skin, regulates your body temperature, and resists odor even after multiple wears. Unlike cotton, which stays wet and causes chafing, merino dries fast and stays comfortable all day. It works in summer to keep you cool and in fall or winter under a mid-layer to trap heat. Look for a 150-weight merino for warm weather and a 250-weight for colder days.
Hiking Pants or Convertible Pants
Regular jeans are one of the worst things you can wear on a trail. They are heavy when wet, restrict movement, and take forever to dry. A pair of lightweight nylon hiking pants like the Columbia Saturday Trail Pants or REI Co-op Sahara Pants moves with you, dries in minutes if you cross a creek, and holds up to brush and rocks. Convertible hiking pants that zip off into shorts are a great choice if you hike in changing temperatures, since you can adjust throughout the day without stopping to change.
Waterproof Rain Jacket
Weather changes fast in the mountains and on longer trails. A packable waterproof rain jacket like the Marmot PreCip Eco or Columbia Watertight II is small enough to fit in a daypack pocket and light enough that you will not notice it until you need it.
Look for jackets with taped seams and a durable water repellent (DWR) coating for real waterproofing. A hood that adjusts is a must so it stays on in wind. Even on sunny days, a rain jacket doubles as a wind layer and emergency warmth layer.
Merino Wool Hiking Socks
Most beginners underestimate how much their socks matter on a hike. Cotton socks hold moisture, bunch up in your boots, and cause blisters by mile two. A quality pair of merino wool hiking socks like Darn Tough Vermont or Smartwool PhD Outdoor cushions your foot, wicks sweat, and prevents hot spots that lead to blisters.
Choose a medium-cushion sock for most day hikes and a heavy-cushion sock for rocky or longer trails. One good pair of hiking socks can make the difference between a comfortable hike and a painful one.
