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, your choice of jacket should lean towards a hardshell. It provides excellent protection against the elements thanks to its membrane, which is both waterproof and windproof. A softshell, while offering many advantages, is not recommended for a long trek where heavy rain can hit. Indeed, predicting the weather over several days is tough, especially in the mountains. It is better to ensure optimal protection with a waterproof jacket.
Hiking trousers for a long trek
Taking several pairs of hiking trousers is a smart move for a multi-day hiking trip. We recommend taking at least two pairs. For example, you can choose a durable, warm pair and pack a lighter second pair, such as zip-off convertible trousers. This allows you to handle all conditions. Your choice naturally depends on the season, the climate, and where you are heading out to hike.
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
Dedicated walking socks are strongly recommended to keep you well protected. They prevent poor moisture management and blister formation. Cotton socks should therefore be avoided. When it comes to your walking boots, it is best to opt for high-cut or mid-cut boots rather than low-cut shoes. They are better suited to situations where ankle support is critical (long treks, technical terrain, heavy backpacks, etc.).
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.
