Key features of technical jackets
Technical jackets are designed to protect outdoor enthusiasts from the elements — wind, rain, snow and cold — while offering optimal comfort and freedom of movement. However, with the huge range of options available on the market, choosing the jacket that best meets your needs can be a challenge. In this article, we'll guide you through the key factors to consider when buying your technical jacket.
Weather protection
Weather protection is paramount during your outdoor activities. Make sure the technical jacket you choose is waterproof to keep you dry in rain and snow. Equally important is a breathable technical jacket that wicks moisture from the inside out, preventing you from feeling overheated during intense effort.
Understanding waterproofing and breathability
The waterproofing of a jacket refers to its ability to protect against external moisture (rain, snow). Expressed in Schmerbers or millimetres (1 mm = 1 Schmerber), it is measured by placing the fabric under a column of water at increasing height and measuring the point at which water penetrates it: the higher the value, the more waterproof the garment. For everyday use or light activities in the rain, a jacket with a waterproof rating of around 5,000 mm to 10,000 mm is generally sufficient. For more intense activities or more extreme conditions, it is recommended to choose a jacket with a higher waterproof rating, ranging from 15,000 mm to 20,000 mm and above.
The breathability of a jacket refers to its capacity to expel water vapour resulting from the skier's perspiration. Two units of measurement exist: the RET (Resistance Evaporative Thermique), where the lower the value, the more breathable the fabric: RET below 6 = highly breathable; RET between 6 and 12 = breathable; RET between 12 and 20 = low breathability. The second unit of measurement is g/m²/24h. In this case, the higher the value, the more effectively perspiration is expelled: 30,000 = extremely breathable garment, 20,000 = very good breathability, 10,000 = breathable, 5,000 = low breathability.
Choosing by activity and conditions
Choose a technical jacket with insulation suited to your activity and the conditions you’ll face. Lightweight "softshell" jackets are ideal for spring and autumn outings, while warmer winter jackets are better for extremely cold temperatures.
Comfort and freedom of movement
Technical jackets are designed to give you freedom of movement. Check that the fit and sleeves let you move comfortably, especially during demanding activities. An adjustable hood helps protect you from the elements without restricting your vision. Look for one that fits well and stays in place as you move. Check what fabric the jacket is made from. Brands often use innovative technologies to improve durability, moisture management and weight. Think about what you’ll wear underneath your technical jacket. If you layer clothing to adapt to changing temperatures, choose a jacket that works with the three-layer system. Wear a thermal base layer first, followed by a fleece jacket or an insulated jacket as your second layer. Add a protective jacket as your third layer. Some technical jackets are designed for specific activities. If you ski, for example, look for a winter-sports jacket with features such as pockets for your lift pass and phone, reinforcements or reflective details for better visibility on the slopes.
