THE WORLD'S WARMEST BASELAYER®

It's warm from the moment you put it on.
The more you move, the warmer it gets.

Over 600,000 units sold. "Heat Love," the brushed underwear that boasts "warmth from the moment you put it on," has been improved with an even thicker fabric for the body, making it warmer than a coat and about three times warmer than a sweater. The clo value, which indicates heat retention, has risen from 0.71 to 0.92.

With its excellent heat generation and heat retention properties, as well as moisture control, even a single layer provides ample warmth and a refreshing feel without causing stuffiness.
It has evolved into a reliable piece of clothing for everyday use, outdoor activities, golf, motorcycling, and other cold environments.

It's warmer than a coat in just one layer.
No need to layer.

The thermal insulation value of clothing that can maintain an average skin temperature of 33°C is 1 clo.
Sweater (100% wool) 0.32 / Winter coat 0.74 (according to our research)

Improved body fabric to be thicker

The fabric in the body has been made thicker and is designed to trap more air between the fibers, preventing body heat from escaping and keeping you warm for longer.
It provides more warmth than a winter coat.

It's warm but easy to move in.

Even though the fabric in the body has been made thicker, it remains easy to move around in.
It is stretchy, allowing you to enjoy sports without stress.
The golf swing is also smooth.

Maintains outstanding comfort.
"Thermogear®"

The outer surface is made of the moisture-absorbing and heat-generating material "Thermogear®".
It has excellent moisture-regulating properties, releasing excess moisture and preventing stuffiness, keeping you feeling fresh and comfortable.

Unique "double loop barrel brushed"

Our unique "double loop barrel brushing" technique evenly brushes the thick pile in all directions.

- Extra thick fabric is used for the body part, making it even warmer.
- The looped brushed fabric stores a large amount of air, preventing heat from escaping and keeping you warm.
- Frictional heat generates warmth even with the slightest movement such as putting your hands through the sleeves.
- Thermogear® moisture-absorbing, heat-generating fiber reduces stuffiness and keeps you warm.

Frictional heat

The more you move, the warmer you get.
The unique, long-pile "double loop barrel brushed" fabric generates heat through friction in response to body movements.
The air pockets prevent the heat from escaping, keeping the inside of the garment comfortably warm.

Moisture absorption and heat generation

The exterior is made of "Thermo Gear," a moisture-wicking, heat-generating material. It converts sweat and other moisture into heat while releasing excess moisture. The interior is dry and feels fresh against the skin.

Insulation and heat retention

It's like an insulating layer that's "wrapped in air."
Large air pockets block heat transfer between the outside air and body temperature.
It creates a layer of warm air around the body, keeping the temperature inside the clothing stable even in cold weather or wind.

Loved by professionals too

The Heat Love series is lightweight and easy to move in, making it perfect for golf. There are different types, and I can wear them in the morning, depending on the weather and temperature, so they are very useful!

Professional golfer Shingo Katayama

In winter golf, wearing too much clothing can make it difficult to swing, but these gloves don't feel too tight and are very easy to move in. I'm sensitive to the cold, so Heat Love has really helped me out.

Ayayo Eguchi Productions

The Heat Love series is great for golf because you can wear just this jacket and a light layer of clothing on top to stay warm, and there are fewer restrictions on movement. I also like that you can choose the material to suit changing temperatures!
