Whether you are a beginner or a seasoned hiker, choose your outfit carefully. It needs to support your effort and protect you from risks like hypothermia or sunstroke. Clothing varies depending on the season, outing type, and weather conditions. Find out what clothes to choose for hiking.
Key takeaways:
- The three-layer system combines a breathable base layer, an insulating mid-layer, and a protective outer shell.
- The choice of trousers depends on weather conditions and the type of terrain.
- Shoe cuff height should be chosen according to the type of hiking
- Essential accessories to complete your outfit.
The three-layer principle
To choose the right clothing for hiking, the most effective approach is to follow the three-layer principle. This means wearing a breathable layer, an insulating layer and a protective layer. You can then remove or add layers according to the weather and your level of exertion.
The first layer is breathable. It consists of T-shirts or technical base layers that wick away sweat. Synthetic fabrics help regulate temperature and dry quickly. Merino wool is another option. It retains warmth even when wet and helps limit odours. Whatever you choose, avoid cotton, as it absorbs moisture.

The second layer provides insulation. It retains body heat by trapping air. This layer is usually a fleece jacket or an insulated jacket. Materials include natural down (for an excellent warmth-to-weight ratio, though it is less effective when wet), synthetic insulation (for better resistance to moisture) and wool (which remains a good insulator even when wet).
The third layer provides protection. Waterproof jackets protect against the elements (rain, snow, wind…). They are waterproof, windproof and breathable. Which hiking jacket should you choose? It depends on how you use it. If you enjoy intense, active outings, prioritise breathability. If you hike in an area prone to rain or snow, focus instead on a highly waterproof membrane.

Which hiking trousers to choose
When choosing hiking trousers, freedom of movement, durability and protection suited to your environment are key. In terms of fabric, natural fibres prioritise comfort, while synthetic fibres offer greater protection. Choose a breathable fabric for warm weather, or an insulating, water-repellent fabric for cold or rainy conditions.
Fit-wise, trousers should be neither too tight nor too loose. An adjustable waistband and reinforced panels (knees, seat) are ideal. Pay attention to practical details like pocket placement, secure zips, or ankle drawcords to seal out debris and water.

The type of trousers you choose mainly comes down to personal preference. Traditional hiking trousers work well in all conditions. Shorts are practical in summer, provided you are not walking through woodland or long grass, where ticks are common. Convertible trousers are therefore a good alternative. Leggings are also an option for short outings.
Although the three-layer principle is often associated with clothing for the upper body, it can also be applied to the lower body. In very cold weather, you can add wool leggings as a base layer. In showers, waterproof overtrousers are recommended.
Which hiking footwear to choose
Choosing hiking clothing also means picking the right socks and footwear. Sock fabric depends on your activity. For long treks or cold weather, wool is ideal. For fast-paced hiking, synthetic fabrics are recommended—they offer a precise fit and superior moisture wicking. Look for a pair with heel and toe reinforcements to prevent blisters.
Hiking footwear needs to provide support, grip and protection. Choose it to suit the shape of your feet, the type of hike and the terrain. In dry weather, opt for footwear with mesh uppers for good ventilation. Closely spaced lugs also provide good grip. In wet weather, choose footwear with a waterproof membrane, such as Gore-Tex, for waterproofing and breathability. Deep, widely spaced lugs also help prevent slipping.
Low-cut shoes are recommended for fast-paced or short outings on relatively even terrain. Mid-cut footwear offers a good balance of support for varied terrain. Finally, high-cut boots provide excellent ankle support and are suited to mountain hikes or carrying a heavy pack. Whatever you choose, make sure the footwear fits the shape of your feet to help prevent blisters and other discomfort.

Essential accessories
To complete your hiking outfit, a few accessories are essential. In sunny weather, pack a lightweight cap or a wide-brim hat. You should also bring sunglasses with UV protection.

In colder or windy conditions, additional accessories come in handy. So what should you wear for hiking on cool or windy days? Opt for a lightweight beanie, thin gloves, and a neck gaiter. A neck gaiter is a versatile essential you can wear multiple ways to stay prepared for changing conditions.
Now you know what clothes to choose for hiking. With these tips, you can pack light while staying fully equipped to hit the trails. Happy hiking!
