How Tight Should Base Layer Be?
The thermal base layer still functions as a novelty, which is why many people approach it uncertainly. Using clothes made of modern fibers is conducive to practicing sports, keeping the body dry, and reducing the abrasions of the epidermis and the formation of unpleasant odors.
Thermal Clothing: Layer System Concept
The layer system has the principle of segregating, in different pieces, the various functions that the clothing needs to fulfill. It has the primary objective of preparing the body for all the climatic changes that may arise. This system is also often known for the principle of three layers, as each of these layers is responsible for the following need:
- Conduct perspiration on the outside; (moisture wicking)
- Keep the ideal body temperature stable; (Heat retention)
- Protect from the elements of nature–rain, wind, snow. (Durability)
Each layer serves a different purpose and works in tandem with the others to keep your skin dry, warm, and comfortable.
First Layer or Inner Layer
Also known as the base layer or second skin, this layer should snugly fit with the body. This one goes well glued to the body. The idea is that it really sticks, without leaving spaces, without gaps (but without getting too tight). The primary function of the first layer is moisture-wicking. It supports regulating your body temperature by moving moisture away from your skin. As water is an excellent thermal conductor, the body will quickly get cold if sweat cannot escape the skin's surface.
Synthetic textile fibers such as polyester/spandex blends offer excellent elasticity with which the base layers are made. Being a snug fit to the body, the first base layer shouldn't be so tight that it potentially restricts the movement. The wrong size can affect its breathability, thus making you uncomfortable. It must stick to the body without disturbing the four-way stretchability of the fiber while maintaining heat retention with the help of fleece lining.
Thermal base layers are lightweight and do not bulge because we must wear them comfortably under our daily clothes. Clothing will keep your body warm but will allow your skin to breathe. A garment that doesn't fit the body will not keep it warm since it will let the cold creep in. Thermajane and Thermajohn's base layers are the perfect choice to gain the benefits of warmth and flexibility without an intimate feel.
The function of the first layer is to expel perspiration from your body to the outer surface of the fabric. This is where it will either evaporate directly into the air if you have nothing else on or be absorbed by the next layer.
The thermal base layer protects the body from cooling down. It is practically every piece of clothing that protects us from the cold. The construction of modern materials used in its production allows for removing moisture from the layer in contact with the skin. Damp underwear gives a very unpleasant feeling, and we are also more prone to chafing.
