Heading out on a long trek requires organisation and thorough preparation. The goal is to pack a minimum amount of clothing for maximum efficiency, focusing on technical and versatile garments. They adapt to all conditions, whether under direct sun or in adverse weather such as rain or wind. Explore the essential hiking clothing to pack for a long trek.
The three-layer system for the upper body
Just like on a day hiking trip, the three-layer system is your best ally when you head out trekking. It can be adapted to changing weather, and it is mainly the choice of materials that differs compared to a short hiking trip.
The base layer wicks away sweat and regulates body heat. For a multi-day hiking trip, merino wool garments are preferred. It offers excellent moisture management and prevents bad odours from forming. You can therefore wear it for several days without any issues.
The choice of the insulating second layer depends on your environment and the climate around you. We recommend opting for a fleece, choosing the right weight based on the temperature. It delivers near-instant warmth. You can also opt for a down jacket, ideal if temperatures are very low, but not recommended during intense exertion.
Finally, a hardshell is the better choice of jacket. Its waterproof and windproof membrane provides excellent protection from the elements. Despite its many advantages, a softshell is less suitable for a long trek where showers may occur. It can be hard to predict the weather several days ahead, especially in the mountains. For reliable protection, choose a rain jacket.
Hiking trousers for a long trek
Having several pairs of hiking trousers is a good idea for a multi-day hiking trip. We recommend taking at least two pairs. For example, you could choose one durable, fairly warm pair and a second, lighter pair that converts into shorts. This helps you adapt to different conditions. Your choice will, of course, depend on the time of year, the climate and where you’re going hiking.
Trousers must meet at least three criteria: durability, water repellency, and breathability. If your trek is more technical, having trousers with reinforcements in key areas is a real plus. A water-repellent treatment to provide basic protection against moisture is also essential (if you expect bad weather, you can always pack additional rain overtrousers). Finally, ventilation zips allow you to significantly improve the breathability of your trousers.
When it comes to fabrics, we recommend choosing synthetic fibres for a long trek. They dry faster, offer better water resistance, and provide enhanced protection when the temperature drops. When hiking over several days, even in summer, mornings and evenings are often cool and damp, making suitable trousers essential. Keep in mind that your trekking clothes must adapt to as many situations as possible.
Foot protection and essential accessories
Walking socks are strongly recommended to protect your feet. They help manage moisture and prevent blisters, so avoid cotton socks. For your walking boots, it’s better to choose high- or mid-cut styles over low-cut footwear. They’re better suited to situations where ankle support is especially important, such as long treks, technical terrain or carrying a heavy pack…
Finally, do not forget to pack several accessories. In summer or warm conditions, you can bring a sun hat or a cap. In winter or cold weather, a beanie and a neck gaiter are essential. Always carry sunglasses to protect your eyes, and opt for models with side shields at high altitudes.
Hiking clothes for a long trek must be durable, versatile, and adaptable to all conditions. In addition to the clothes you wear and spare items, you can bring an outfit dedicated to the bivvy. Choose lightweight clothing to avoid overloading yourself throughout your hiking trip.
