HEATTECH is a revolutionary form of innerwear. The secret behind the warmth of HEATTECH actually isn’t a secret at all, but a case of science and immense amount of research. HEATTECH’s most vital quality is that it uses moisture released by the body to re-emit heat.
It does more than just keep you warm and comfortable.
Light yet warm. Doesn’t feel bulky, so you can wear it all day.
