HEATRUB antibacterial deodorant model
It's warm from the moment you put it on.
The new model has improved details while retaining the basic performance. It also has antibacterial and deodorizing properties.
[What is Heat Love?]
The ultimate cold weather protection. Just one piece is enough to keep you as warm as a coat.
It boasts excellent heat generation and heat retention. The two-layer structure combines the heat generation and heat retention properties of the unique fleece lining with the moisture control properties of Thermogear, providing ample warmth and excellent ease of movement even when worn alone.
This is a classic winter wear that doesn't require you to dress too thickly.

This is where the new model has evolved.

Mock fabric
The mock fabric has been changed to a firmer one. The height has also been increased by about 1cm to make it easier to prevent cold air from entering. This has resulted in a beautiful silhouette even when the neck is exposed.
sleeve
In response to complaints that the sleeves were too short and cold, the sleeves have been extended by 1.5cm to provide a firm barrier against the intrusion of cold air.
Plus antibacterial treatment

Good news for those who sweat a lot. "Heat Love is too hot and makes me sweat..." We've added a great feature for those people. Polygiene antibacterial and deodorizing treatment means no more odor.
Just the warmth of a coat.

"Heat Love" is a next-generation smart undergarment with high heat generation and heat retention properties that provides approximately twice the warmth of a sweater and the same warmth as a coat. *The thermal insulation value of clothing that can maintain an average skin temperature of 33°C is 1 clo, which indicates the thermal resistance of clothing. Example) Sweater (100% wool): 0.32 / Winter coat: 0.74 (according to our research)
Heat consumption | Heat retention rate | Intrinsic clo value | |
Heat Love | 5.1 | 55.90% | 0.7 |
Normally brushed | 5.3 | 54.60% | 0.67 |
fleece | 5.9 | 49.70% | 0.55 |
cotton pile | 7.7 | 34.00% | 0.29 |
Frictional heat

The long-pile brushed fabric (unique "double-loop barrel brushed") generates frictional heat with every movement. The large layer of air prevents heat from escaping, maintaining a higher temperature inside the garment.
Moisture absorption and heat generation

The outer layer is made of the moisture-wicking, heat-generating material "Thermo Gear." It has excellent moisture-regulating properties, releases excess humidity, and prevents stuffiness, keeping you feeling fresh and comfortable.
Insulation and heat retention

It blocks heat transfer between the outside air and body heat, creating a large layer of air to maintain the temperature inside the garment.
