This thermal underwear provides top performance for sports and leisure activities in all winter temperatures and in cool winter and summer days. It features a body mapping system that allows thermal regulation and moisture transfer at the sweat zones. More than that, the underwear has thermal activity properties, meaning that the temperature control system is independent of external conditions and it aims to offer a guarantee against the cooling or warming of the body. It also features special three-dimensional elastic layers that optimise the support and control muscle pressures, to ensure better blood flow during exercises. Last but not least, freedom of movement for every activity level is ensured by the three-dimensional elasticity and double-seam technology.
