Keeps warmth in with a 3-layer structure To enhance heat retention, the fabric is carefully knitted with a special 3-layer structure. It traps the warm air warmed by body temperature and shuts out cold air from the outside, boasting the best heat retention. Click here for more details on the 3-layer structure fabric ≫ 2. Less likely to feel cold from sweat Uses polyvinyl chloride "Dantron", which has excellent quick-drying and moisture-permeability properties. It releases the unpleasant stickiness caused by sweat and moisture, and does not leave moisture on the skin side. Because body heat is not taken away, the part that touches the skin is always dry and does not easily feel cold from sweat. 3. Deodorizing function Absorbs and neutralizes odors such as ammonia, which causes sweat and aging odors, and eliminates them. 4. Prevents static electricity and eliminates dust adhesion Suppresses static electricity generated during putting on and taking off, and reduces dust adhesion caused by static electricity, which is also a cause of dirt, and unpleasant clinging. 5. Combination of 3-layer and 2-layer structure The sleeves have a 2-layer structure, so they can be worn neatly as an inner layer. This design is especially recommended for those who are concerned about the looseness of the armpits and arms, and for those who feel that other 3-layer underwear is "too warm". ※ Men's trousers and tights have a front opening. ※ The waist elastic itself is sewn on, and the elastic cannot be removed by itself. ※ Uses antibacterial and deodorizing material Cuteley (composite fiber) Remarks: Made in Japan Manufacturer: Kenshin Co., Ltd. ※ The products worn by the mountaineering team are slightly different in material and specifications from the current products.
