Summer mountain hiking is a rewarding activity that lets you discover stunning landscapes and recharge in the heart of nature. However, to make the most of the experience, choosing the right kit is essential. Mountain conditions can vary considerably, even in summer, and being properly equipped is crucial to staying comfortable and safe. Here are all our tips for choosing the ideal outfit for hiking in the mountains during the summer season.
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 kit to your specific needs. Here are a few criteria 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 enough. For a more demanding hike or a multi-day trip, it's crucial to choose clothing that provides good support, optimal breathability and protection against the elements.
- Altitude: The higher you go, the lower the temperature. On average, it drops by 6°C for every 1,000 metres gained. Even in summer, you can encounter snow in the mountains, so it's important to plan for clothing that handles temperature swings.
- Your personal sensitivity to cold: Some people feel the cold more than others. It's important to know your own tolerance so you can choose clothing that keeps you both warm and dry without overheating. If you're particularly sensitive to the cold, don't hesitate to pack extra layers even if the forecast looks favourable.
Choosing your summer hiking clothing: tops
For a solid summer hiking outfit in the mountains, 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. On top of that, wven in summer, the three-layer rule still applies to avoid nasty surprises. Pack a mid-layer, such as a lightweight breathable fleece, to insulate against the cold when needed. This layer will come in handy during breaks or if temperatures drop. Finally, it's crucial to have a jacket that protects you from the elements (wind, rain…). A water-resistant jacket may be enough, but a fully waterproof hiking jacket is preferable, as a heavy downpour or storm can arrive quickly. Make sure the jacket is also breathable to prevent sweat from building up inside.
Which fabrics should you choose?
T-shirts in synthetic fabrics are breathable and quick-drying, making them perfect for your summer mountain hiking outfit. These materials allow excellent moisture evaporation, helping to maintain a comfortable body temperature. For multi-day hikes, merino wool offers excellent thermal regulation and naturally resists odours, letting you wear the same t-shirt for several days without discomfort. Merino wool is also very soft and won't cause irritation, even when worn directly against the skin. On the other hand, beyond a simple stroll, avoid cotton — it retains moisture and dries slowly, which can lead to rapid chilling and an uncomfortable feeling.
Choosing your summer hiking clothing: bottoms
- Shorts: Hiking shorts are perfect for warm days, offering great freedom of movement. However, they're not suited to all weather conditions, particularly at high altitude where temperatures can be low. Shorts with zipped pockets can be very handy 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. Some models feature reinforcements and ventilation systems for added comfort.
- 2-in-1 trousers: Offering great flexibility, these trousers can be converted into shorts as needed, making them ideal for significant temperature changes. They let you adapt easily without having to change your whole outfit.
The best footwear 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 moisture-wicking soles and 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 rough terrain or long hikes. They provide better ankle support and increased protection against impacts. Don't overlook waterproofing in case of rain either. To find out more, discover how to choose your hiking shoes.
Essential gear for summer mountain hiking
To complete your summer mountain hiking outfit, some accessories can prove very useful:- Cap: A cap to protect you from the sun and prevent heatstroke. It should be made from a breathable material to avoid heat build-up.
- Neck gaiter and gloves: A neck gaiter and lightweight gloves can be worth packing, especially for early morning starts and shaded terrain.
- Sunglasses and sunscreen: Protect your eyes and skin from 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 clothing.
- Hiking poles: They can provide extra support on rough terrain and reduce muscle fatigue. Adjustable poles are practical for adapting to different terrains and gradients.
- Backpack: Go for a lightweight backpack with good ventilation and enough compartments to organise your gear.
