These running thermal wear are designed based on human engineering during running, verifying skin temperature changes in cold conditions. The main material is a lightweight, highly stretchable brushed knit fabric. PERTEX QUANTUM fabric is used from the thighs to the waist to enhance windproof effects, and the area from the knees to the hem, where movement is intense, is constructed with stretch knit. The waist features five pockets using power stretch mesh, plus a belt for storing outerwear with side access. This allows for smooth storage operation without stopping. The silhouette is a tight-fit design that eliminates bulkiness. It features a stylish design that makes the hip line less noticeable, while also incorporating a tapered pattern that considers leg movement. Electrostatic care design suppresses the generation of unpleasant static electricity. Ventilation is equipped on both sides to control the temperature inside the garment. This is technical wear that provides comfort with moderate heat retention while suppressing overheating during winter running.
