About HEATTECH

1

HEAT ABSORPTION

Water vapor form the body is absorbed by highly absorbent 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.
