Hiking in the mountains in summer is an exciting activity that lets you discover breathtaking landscapes and recharge in the heart of nature. However, to make the most of this experience, choosing the right outfit is essential. Mountain conditions can vary considerably, even in summer, and it's crucial to be well equipped to stay comfortable and safe. Check out all our tips for choosing the ideal outfit for summer mountain hiking.
Key criteria for choosing your hiking or trekking outfit in the mountains
Everyone has their own approach to hiking, and it's essential to tailor your outfit to your specific needs. Here are a few criteria to consider to help you make the best choice:
- The duration and intensity of the hike: For a short, low-intensity hike, simple and comfortable clothing may be sufficient. For a more demanding hike or a multi-day outing, however, it's crucial to choose clothing that provides good support, optimal breathability and protection against the elements.
- Altitude: The higher you climb, the lower the temperature drops. On average, it falls by 6°C for every 1,000 metres. Even in summer, you may encounter snow in the mountains, so it's important to prepare clothing suited to temperature variations.
- Your personal sensitivity to the cold: Some people feel the cold more than others. It's important to know your own sensitivity so you can choose clothing that keeps you both warm and dry without causing overheating. If you're particularly sensitive to the cold, don't hesitate to bring extra layers even if the weather looks mild.
Choosing your hiking clothing for summer: the top half
For a good summer mountain hiking outfit, go for a lightweight, breathable t-shirt. Its main job is to wick moisture away from your body and keep you dry. A t-shirt with UV protection is also recommended, as the sun is more intense at altitude.
Furthermore, even in summer, the three-layer rule still applies to avoid unpleasant surprises. Bring a mid layer, such as a lightweight, breathable fleece, to insulate yourself from the cold when needed. This layer will come in handy during breaks or if temperatures drop.
Finally, it's essential to have a jacket that protects you from the elements (wind, rain…). A water-resistant jacket may be sufficient, but a hiking jacket that is fully waterproof is preferable, as a heavy downpour or storm can strike quickly. Make sure this jacket is also breathable to prevent sweat build-up inside.
What materials should you choose?
T-shirts made from synthetic fabrics are breathable and quick-drying, making them perfect for your summer mountain hiking outfit. These materials allow excellent sweat evaporation, helping to maintain a comfortable body temperature.
For multi-day hikes, merino wool offers excellent thermal regulation and naturally resists odours, allowing you to wear the same t-shirt for several days without discomfort. Merino wool is also very soft and causes no irritation, even when worn directly against the skin.
For anything beyond a simple stroll, avoid cotton, which retains moisture and dries slowly, as this can lead to rapid chilling and a feeling of discomfort.
Choosing your summer hiking clothing: the bottom half
- Shorts: Hiking shorts are perfect for warm days, offering great freedom of movement. However, they are not suited to all weather conditions, particularly at high altitude where temperatures can be low. Shorts with zipped pockets can be very practical for keeping your valuables secure.
- Trousers: Essential for high-altitude hikes, hiking trousers protect against wind, showers and cooler temperatures. Hiking trousers are designed to be lightweight, durable and unrestricting of movement. Some models feature reinforcements and ventilation systems for added comfort.
- 2-in-1 trousers: Offering great versatility, these trousers can be converted into shorts as needed, making them ideal for significant temperature changes. They allow you to adapt easily without having to change clothes.
The best shoes for summer
The walking shoes in your summer mountain hiking outfit must be breathable enough to prevent your feet from becoming soaked in sweat, which increases the risk of blisters. Look for shoes with soles designed to wick away moisture and made from lightweight, breathable materials. Make sure they offer good support and grip for varied terrain.
Low-cut shoes are often preferred in summer for their lightness and better ventilation. They are ideal for less rugged terrain and short hikes. Mid or high-cut shoes, on the other hand, are better suited to rugged terrain or longer hikes. They offer better ankle support and increased protection against impacts. Don't overlook waterproofing in case of rain.

Essential gear for summer mountain hiking
To complete your summer mountain hiking outfit, certain accessories can prove very useful:
- Cap: A cap to protect you from the sun and prevent heatstroke. The cap should be made from breathable material to prevent heat build-up.
- Neck gaiter and gloves: A neck gaiter and lightweight gloves can be useful to bring, especially for early-morning starts and on shaded terrain.
- Sunglasses and sunscreen: Protect your eyes and skin from the intense UV rays at altitude. Choose sunglasses with high UV protection and a sweat-resistant sunscreen. Apply it to all areas of your body not covered by your clothing.
- Hiking poles: They can provide extra support on rugged terrain and reduce muscle fatigue. Adjustable poles are practical for adapting to different terrains and inclines.
- Backpack: Go for a lightweight backpack with good ventilation and enough compartments to organise your gear.
