About HEATTECH

1

HEAT OF ADSORPTION

Water vapor form the body is adsorbed by highly adsorbent fiber. The energy from this moisture is converted to heat, meanig the fabric itself has a warming effect.

2

HEAT RETENTION

HEATTECH uses fibers one-tenth the fitness than a human hair to create lots of highly insulating layers, preventing warm air from escaping.

3

MOISTURE WICKING

HEATTECH is made up of a combination of several different fibers, so it's not just bio-warming. It also has a high content of absorbent fibers to wick away moisture.

※Functions vary for some products.

4

QUICK-DRY

The polyester fiber absorbs sweat quickly and dries.

※Functions vary for some products.

5

TEXTURE

The ultra-fine fibers provide a smooth feel on the skin. In addition, vegetable oil is kneaded into the fiber to make it moist and soft to the touch.

※Functions vary for some products.
