HEAT RUB

Heat Love, the underwear that keeps you warm from the moment you put it on and has sold over 600,000 units, has undergone a major evolution.

By making the body fabric thicker,
The clo value, an index of thermal insulation performance, has improved from the previous 0.71 to 0.92 .

It provides a "warmth in one layer" experience that exceeds that of a typical winter coat (0.74).

Winter golf, touring,
This is a next-generation base layer that you can rely on for a wide range of situations, from fishing to commuting and walking.

Warmer than a winter coat

This one piece is about three times the size of a sweater.
Warmer than a winter coat.

The body has been redesigned with extra thick fabric.
Designed to trap air in multiple layers to prevent heat from escaping.
The clo value, an index of thermal insulation performance, has improved from the previous 0.71 to 0.92 .

It's warm enough that you don't need to layer up even on chilly days.

Moisture absorption and heat generation

The exterior is made of moisture-absorbing, heat-generating material "ThermogearⓇ".
It captures water vapor (the precursor to sweat) emitted from the body and converts it into heat.

The material itself has a high moisture-regulating effect,
Quickly releases excess moisture that tends to accumulate inside clothing.

Frictional Heat

The brushed "pile" creates multiple air pockets that reduce heat exchange with the outside air.

It holds both body heat and fever,
Maintains a higher temperature inside clothing.
