Do you need to buy a whole hiking outfit before going to the mountains? You can start with clothes you already own on a low-mountain day hike. Knowing which fabrics and layers can cause problems helps you choose safely.
Here's how to assess your own clothes, what to buy first and what to leave at home. Use this as a starting point before investing in specialized clothing.
What makes clothing suitable for hiking?
Start with what happens when the fabric gets wet. Cotton retains sweat and rain and dries slowly. Even on a low mountain in summer, a sweat-soaked cotton shirt can leave you unexpectedly cold in the wind.
Durability and resistance to abrasion also matter. Thin stretch fabrics can tear on rocks and branches, and they offer little skin protection if you land on your hands or knees.
Check each item for how it handles moisture and how it holds up to abrasion.
What you can use from your closet
Base layer
Fabric matters most where the clothing sits directly against your skin.
Good options
- A quick-drying polyester or nylon sports shirt you would wear for running or the gym.
- A wool-blend top. Wool tends to retain warmth when wet.
Leave at home
- A 100% cotton T-shirt, especially a short-sleeved one worn on its own.
- A cotton-blend casual top.
Read the care label and consider how quickly the garment actually dries. Polyester, nylon and some blends can work well. Avoid fabrics that stay damp against your skin.
Midlayer
This layer keeps you warm. A fleece jacket or lightweight down vest you already own can often work.
Good options
- A fleece jacket or vest. Most are polyester and retain some warmth when wet.
- A lightweight synthetic-insulated jacket. It handles moisture better than down.
Use with care
- A down jacket. It loses warmth quickly if it gets wet. It can work on a low mountain in reliably dry weather.
- A denim shirt jacket, which is heavy and slow to dry.
Pants
Check the fabric and how freely you can move in it.
Good options
- Stretch training pants or joggers in polyester or nylon.
- Synthetic cargo pants that move easily and dry quickly.
Leave at home
- Jeans. Cotton denim is heavy, gets heavier when wet and restricts movement. It can also increase the risk of hypothermia.
- Skinny pants or tight cotton trousers. They restrict knee movement and can tire you out on trails with lots of steps.
On a trail, you often have to lift your knees high. See whether you can comfortably bend them past 90 degrees before deciding what to wear.
Socks
Look at thickness and fabric.
- Thin cotton socks can hold moisture and rub, which can contribute to blisters.
- Quick-drying socks similar in thickness to running or hiking socks are a reasonable starting point.
Socks wear out and are relatively inexpensive, so they're a sensible early purchase.
What to add for your first hike
Prioritize two things when using clothes from your closet.
Rainwear
Mountain weather can change quickly. An umbrella takes up a hand and offers limited protection in the wind. Bring a hooded waterproof jacket and rain pants suited to the conditions.
A regular windbreaker treated with waterproof spray may handle a brief drizzle. It offers limited protection in sustained rain or strong wind. Hiking rainwear gives you a more dependable first-trip setup.
Hiking shoes
Sneakers can work on some routes. Hiking shoes differ in sole stiffness, grip and ankle support.
Wet roots and rocks can be slippery in any footwear. A running shoe with good tread may suit a short, dry, firm trail. Rocky ground, mud and steep descents call for footwear with grip and support suited to that terrain.
If you use shoes you already own, start with a short, dry and well-maintained trail. Turn back if you keep slipping or your shoes do not fit securely.
How season and weather change what you need
Temperature, weather and the mountain area determine how much your current clothes can handle. Use these benchmarks as a starting point.
Where everyday sportswear can work
- A low mountain in clear spring-to-autumn weather, generally below 1,000 m.
- A day when the trailhead is expected to be at least 15°C.
- A route of about three to four hours round trip.
When to reconsider your clothing
- It often gets cooler as you climb. A drop of about 0.6°C per 100 m is a rough climate estimate. Check actual conditions for the area.
- Ridges and summit areas can be windy.
- From autumn onward, especially October and November, the summit may be much colder than the lowlands.
Check regional forecasts and warnings, and consult a mountain-area forecast where available. Compare temperatures, wind and rain at the trailhead and on higher sections the day before and the morning of your trip.
Common clothing mistakes on a first outing
Avoid these combinations.
- Jeans, a cotton T-shirt and a thin hoodie. Cotton can hold moisture and leave you cold during stops or in the wind.
- Sandals or thin-soled flats. Thin or smooth soles may give you little grip and protection on rocky descents.
- A folding umbrella as your only rain protection. An umbrella occupies one hand and provides limited coverage in wind-driven rain.
These choices make a hike more tiring or riskier if you get wet. Feeling unexpectedly cold or exhausted on your first trip can put you off hiking, so prepare for a comfortable outing.
What to do next
Start with quick-drying sportswear and a fleece. Add suitable footwear, waterproof layers and the other essentials, including a map and compass, headlamp, food and water. Nordwand's Base Camps can help you ask people about clothes for a particular trail.
