・As warm as seven layers of cotton underwear
Using Toyobo's eks®, a moisture-absorbing, heat-generating fiber, we have created a garment that provides "the warmth of seven layers of cotton underwear."

・Superb brushed material with a soft feel
The side that comes into contact with the skin is shirred evenly to create a uniform brushed fabric.

・Amazing stretching
Even though the fabric is thick, it is stretchy enough to allow for easy movement.

暖かさ、着ごこち、ストレッチ性においてこだわり抜いたアイテムです。足首もしっかり暖める10分丈。

*The "warmth equivalent to seven layers of cotton underwear" is stated based on a comparison of our own products with measured heat retention values.

About the product

The warmest in HOTMAGIC history: "Kiwame"
This one piece provides the warmth of seven cotton undershirts.

01. Warmth equivalent to seven layers of cotton underwear
"Kiwame" is approximately 1.4 times warmer than conventional HOTMAGIC products.
This is equivalent to the heat retention of seven layers of regular underwear (according to Gunze research). The difference is clear even when comparing thickness.
Even when it's cold outside, you can stay comfortable with just this inner layer.

02. The fiber itself generates heat [eks®]
The fabric uses eks®, which generates heat by absorbing sweat and other moisture. It also has excellent moisture release properties, and is warm and dry without the stuffiness.

[eks]® is a registered trademark of Toyobo Co., Ltd.

03. No side seams

There are no seams on either side, so it fits comfortably to your body without being stiff.
Even though the fabric is thick, it fits well, so you won't feel stressed even if you wear it in layers.
Fewer seams also reduce the tingling sensation on dry winter skin.

04. Excellent stretchability

We focused on creating a light elasticity that does not hinder movement.
It stretches surprisingly well, so it doesn't feel bulky when you put it on or take it off.
It provides a stress-free wearing experience.

05. Japanese-made brushed technology
The fine brushed fabric on the skin side is soft and rich to the touch.
We pursued the highest quality by using shirring (fleece-brushing) that is possible only because of Japanese technology. We deliver the ultimate luxury that can only be enjoyed in the cold winter.
