Among the hundreds of POLARTEC fabrics,
"POLARTEC ALPHA" is positioned as the highest peak of "thermal clothing that can be acted upon".
In this special order, the "POLARTEC ALPHA" was used in all three types.

"Alpha" was originally the code name of the U.S. Army Special Operations Forces. In the U.S. military, conventionally,
We have used synthetic filling, which is an alternative to down, as an insulation Material.
However, due to its characteristics, it required a high-density outer and inner fabric, which significantly reduced breathability.
That's why POLARTEC ALPHA was developed. Its lightweight, compression, quick-drying, and heat retention properties are the same as traditional synthetic padding, but it efficiently releases excess heat and moisture trapped in the garment, maintaining a comfortable environment at all times.

What is even more noteworthy is that STONEMASTER used the "POLARTEC ALPHA" for product dyeing.
Because it is an ultra-fine fiber, it is difficult to adjust the processing temperature, and this Material, which is considered to be more delicate to handle than general fleece,
This is the first time that it has been established as a product.

In addition, the characteristics of product dyeing create an exquisite sense of bite and puckering.
As you wear it over and over again, the color will gradually fade and change into your own texture.
This special order is a special collection that incorporates high-performance Material into products to achieve both functionality and texture.
