HEATTECH
WHAT IS HEATTECH?
Innovative Thermal Clothing Technology.
Fibers absorb water molecules emitted from the body.
Energy from molecules is converted into warmth.
Thin, light and warm.
Three types of high-function
innerwear with a choice of warmth.
A light, thin base layer
that keeps you warm.
Approximately
1.5 times* warmer.
*Calculated based on the CLO value that measures heat resistance of clothing. Compared to regular HEATTECH.
Approximately
2.25 times* warmer.
*Calculated based on the CLO value that measures heat resistance of clothing. Compared to regular HEATTECH.
Lineup
