Functional clothing for 100% result: Layer clothes according to the onion pattern
Modern synthetic materials that favorably combine waterproofness, breathability and light weight ensure that you are neither too cold nor too warm. You will wear three basic layers. In case of changes in the weather, you can easily throw off the layer or change clothes and you will still remain comfortable. And so that you don't kill the function of a perfect quick-drying t-shirt with a non-breathable jacket, make sure that the individual layers also support thermoregulation.
The second layer keeps your body temperature in optimal comfort
The role of insulation layer is to maintain thermal comfort and most often it will be sweatshirts made of fleece and microfleece. Clothing in this layer should be light, flexible and breathable to support the functions of the first layer. However, it must not lose its ability to insulate heat. Sweatshirts with a so-called grid structure are also popular.
The third layer protects you from rain and wind
The third layer of clothing serves as protection against adverse environmental influences. Water resistance and wind resistance while maintaining good breathability are important. For wind protection, you can rely on clothing made of softshell material, for example.
If you are looking for reliable protection against water, choose jackets and pants with a membrane and taped seams.
Do not look for 100% waterproofness in functional clothing, it can only be ensured with a thicker plastic raincoat. However, we recommend it only in a state of extreme emergency. When moving in such plastic, you would quickly find out that in addition to being completely waterproof, the plastic is also 100% non-breathable. Your heat and sweat have nowhere to escape and you end up still wet anyway. Not from the rain, but from your own sweat.
So that the top layer does not destroy the functionality of the previous layers in sweat removal, this must also breathe well. The permeability of the material for water vapor (MVRT) indicates how many grams of steam evaporate through 1 m² of material in 24 hours (g/m²/24 h). The higher the MVTR value, the more breathable the material is (ISO 2528).
What breathability value is ideal for clothing for mountain hiking?
Low and medium intensity of movement - from 5,000 to 10,000 g / m² /24 h For example, it will be a walk in city, easy hiking, flat and slightly undulating terrains.
Difficult terrains and high intensity of movement - over 10,000 g / m² /24 h This will be mountain and alpine terrains with high elevations, rocky terrain, all-day demanding ascents.
Mountain pants hiking
The layering of clothing on the legs is more a matter of winter hiking, ski pants (thermal underpants) or skialpe (top thermal insulation shorts or skirts). You wear hiking pants directly on the body and fulfill the function of a third, protective layer.
So choose to protect you from wind and water, excellently breathable and quick-drying and should not restrict your movement, for example elastic softshell with membrane.
