Technologies Aktiv-Bund® The highly elastic cuff ensures perfect fit without constricting. Two-Step 3D-BionicSphere® System The high-tech knitting technology ensures optimal grip and climate comfort. The different ribs and surface constructions support and transport moisture as well as warmth. ISO-Pad Targeted insulation of individual body parts against ambient coldness can prevent the body from getting cold. This is why ISO-Pads over the hipbones retain body heat that is necessary to guarantee interior organ functionality. Innerlap AirConditioning Zone® The inner thights are less reactive to the cold. Here, woven mesh with zero insulation function allows air to circulate and aids cooling as soon you start to sweat. ExpansionKnee The accordion principle behind the {ExpansionKnee:sup:false} improves its insulating character rather than losing it when the knee is bent. A highly flexible system of chambers and channels provide insulation by storing warm air inside. 3D-BionicSphere® System at the tailbone The sweat of the lower back area is conducted through the 3D-BionicSphere® System to the tailbone for evaporation. The SweatTraps® on the lower back are targeted specifically at catching sweat flowing toward the buttocks. This first phase, which often leads to friction sores, is interrupted before it can even begin. ISO-Base During movement the pants are stretched over the seat area, when sitting bodyweight pushes the material together. In both these situations, cold bridges can occur. The anatomically formed ISO-Base has special air channels that trap body heat and prevent the large gluteal muscles from undercooling.
