You should choose the best material for the scene and use!How to choose a warm innerwear?
The key to choosing a warm innerwear is to select the most suitable material for the scene and purpose for which it is worn. For everyday use, natural materials such as cotton, wool and silk are recommended. They are less likely to cause skin irritation and feel good against the skin. On the other hand, when worn outdoors or for sports, those made of special polyester and other chemical fibers are highly functional ◎ In addition to their high level of heat retention, many have moisture absorption and quick-drying properties, so there is little worry about cooling the body in cold outdoor environments.
If in doubt, choose a warm innerwear made of wool blend, a natural functional material!
Wool is said to be a functional natural material, with high moisture absorption properties that keep the body warm while allowing moisture to escape. For this reason, it is a popular material in the warm innerwear industry, with the thicker ones used in cold climates and for outdoor use, and the thinner ones used for daily use.
From here, we will introduce two categories of warm innerwear: everyday use and outdoor use. Let’s start with the daily use category.
Warm innerwear for daily use 1UNIQLO 'HEATTECH'
It is no exaggeration to say that there is no one who does not know about UNIQLO’s HEATTECH. By blending ultra-fine fibers with vegetable oil, the texture is moist and smooth, making it comfortable to wear on bare skin. In addition to long-sleeved and short-sleeved variations, the tops come in a variety of neck designs, including crew neck, V-neck, and turtleneck. In addition to white, black, and gray, they are also available in beige, which is close to the color of the skin, so they can be arranged to match the design of the clothes worn over them. In addition, the sleeves are set at 9-minute lengths, calculated to prevent the inner lining from being seen through the cuffs. In addition to tops, HEATTECH products are also available in tights, pants, and socks, so you can find products to meet your needs for protection against the cold, such as particularly cold feet, as only the king of UNIQLO can.
The HEATTECH series also includes a series with high levels of cold protection. The “Kyokyu Warm” series offers 1.5 times the heat-retaining properties of HEATTECH thanks to a raised inner lining. Not only is it warmer, but it also has moisture absorption and desorption functions to keep you dry. The soft yarn used for the backing provides a smooth, comfortable feel against the skin.
