Softshell jackets are generally made from synthetic fabrics such as polyester or nylon, in a wide variety of weights and thicknesses. These materials are often blended with elastic fibers such as elastane to offer greater elasticity, crucial for dynamic movements in climbing or mountaineering.
One of the main advantages of a softshell jacket is its ability to offer a balance between weather protection and breathability. Designed to be less waterproof than hardshells, softshells allow better evacuation of perspiration, which is ideal during intense exertion when the body generates a lot of heat.
The weight of a softshell jacket is an important criterion, especially for activities where every gram counts, such as mountaineering or long-distance hiking. Lighter models are preferable for these activities, while for colder conditions, a thicker, less compressible jacket may be advantageous.
For hiking and trekking, a softshell jacket must offer good wind resistance and waterproofing to cope with rapid weather changes. An adjustable hood and well-placed pockets for easy access to personal belongings are assets.
Climbers and mountaineers will benefit from a jacket with great freedom of movement, adjustable cuffs so as not to obstruct vision of hands and equipment, and enhanced abrasion resistance, especially on exposed areas such as shoulders and back.
In winter sports, the softshell chosen must combine insulation and breathability to manage effort on the way up and protection from the cold on the way down. Features such as thumbholes and an integrated snow skirt can help.
Waterproof zippers, easy-to-handle adjustments even with gloves, and reinforced seams are details that can greatly influence a jacket's functionality. Don't underestimate the importance of these small details, which can make a big difference to a jacket's comfort and efficiency.
The cut of the jacket must be adapted to the morphology and specific movements of the activity practiced. A cut that's too tight will restrict your movements, while one that's too loose could interfere with your equipment and reduce the effectiveness of protection against wind and cold.
Finally, consider the durability of the product. A good softshell jacket must be able to withstand the wear and tear of intensive mountain use. Care of the jacket is also an aspect not to be neglected to guarantee its longevity, with specific washing and care instructions to preserve the technical qualities of the fabric.
In conclusion, choosing the right softshell jacket requires careful consideration of the type of activity practised, the expected climatic conditions and your specific needs in terms of mobility and protection. A good understanding of the different technologies and features will help you make an informed choice that will significantly enhance your comfort and performance in the mountains.
