The second layer performs the most important function of thermoregulation of the body due to air exchange in combination with absorption and removal of moisture.

The second layer of thermal underwear with flat seams «Varan» from the company Mordor Tac is made of synthetic fabric of the type «waffle» optimally providing thermoregulation and perspiration.

«Varan», due to its anatomical design, fits the body, has thermal insulation properties and is designed to be worn as a single layer of thermal underwear at moderately cold temperatures and as a second layer for low temperatures.

The operating temperature range, taking into account the use of a layer system, is from +5 °C to -15 °C.
