1. Introduction | Three things to look for in winter pants
Warm pants are essential in cold weather, but simply being thick can make you look heavy and restrict your movement.
What's important for adult women is a balance of warmth, lightness, and a beautiful silhouette. For this reason, we would like to draw your attention to pants made of "heat-generating material + brushed fabric."
In this article, we will compare the differences between wool, fleece, fleece, and thermal pants, and introduce how heat-generating materials work, the secret to their comfort, why they are warm but don't make you feel bulky, and stylish winter outfits that suit the adult generation.
2. Comparing wool, brushed-lined fabric, and fleece
Each of the typical materials used for winter pants has its own advantages and disadvantages.
It has excellent natural heat retention and moisture control properties, but it can be itchy and difficult to handle.
The lining is brushed to trap air and provide warmth, but it can become fuzzy and bulky with wear.
While it is light and warm, its disadvantages are that it is easily permeated by wind and tends to create a bulky silhouette.
Compared to these, the "heat-generating material + brushed pants" are a well-balanced pair of pants that can be worn both for a smart look and for keeping you warm, as they are highly insulating while remaining relatively thin.
3. How heat-generating materials work (what is moisture-absorbing heat generation)
Heat-generating materials use the mechanism of "moisture absorption and heat generation," whereby fibers generate heat when they absorb moisture from the body.
It generates a slight heat without sweating, using the moisture naturally released from your skin.
It is thin but still warm and doesn't get stuffy.

By the way, have you ever heard the expression "zukansoku-netsu" (cold head, warm feet) ?
The human body is structured so that the temperature of the upper body, where organs such as the heart and lungs are located, is higher, while the area around the legs is relatively prone to getting cold.
It is said that keeping this temperature difference between the top and bottom as small as possible is important for maintaining a healthy body temperature balance.
The calves and soles of the feet in particular are so closely related to blood flow that they are called the "second heart."
Warming your lower body improves circulation throughout your body, warming you from the inside out.
That's why, when choosing winter pants, it's important to think about warming your legs.
Heat-generating material combined with brushed pants is the structure that is most suited to this idea of a cool head and warm feet.
Furthermore, the heat-generating material uses yarn that combines highly absorbent rayon and acrylic, which has excellent heat retention properties.
The rayon absorbs moisture from the body, generating heat, and the acrylic traps that heat, preventing it from escaping.
Although it is thin, it is very warm and keeps you comfortably warm.
4. Brushed and sheared for a smooth and comfortable fit
The warmth of fleece lining is appealing, but if left as is, it can become fuzzy and rough.
The key to this is shearing . By smoothing the pile, a smooth feel and a high-quality feel are created.
Fleece-lined items that remain comfortable even when worn for long periods of time may have been treated with this process.
5. Why it's warm but doesn't make you look bulky
A common problem with winter pants is that they are warm but make you look fat.
These pants are made of heat-generating material and brushed fleece, and while the fabric is dense, it is still thin, making the lines of your legs look slimmer.
Furthermore, if you choose a silhouette that makes your legs look slimmer, such as a center crease, tapered, or semi-flared style, you can expect to look slimmer and your legs will look longer.
6. Pilling and stiffness are common problems with cheap pants
Even if low-priced warm pants look similar, these types of problems tend to occur.
7. Why B-Three pants combine a beautiful silhouette with warmth
It's warm but doesn't look heavy.
B-Three's winter pants will make that dream come true.
It uses moisture-absorbing and heat-generating yarn (rayon x acrylic) that absorbs moisture from the body and generates heat.
The rayon generates heat and the acrylic wraps around it, making the garment thin yet warm and comfortable to wear without feeling stuffy.
In addition, the surface is smoothed by brushing and shearing, giving it a fluffy, airy and elegant silhouette.
The high-density stretch material naturally fits the movement of your legs, providing light, fatigue-free warmth that lasts.
The design features increased fiber density, making it less likely to lose its shape or pill, and it also has the added benefit of maintaining its beauty for a long time.
This is a piece that doesn't compromise on either "warmth" or "beauty."
