Keeps warmth in with a 3-layer structure The fabric is carefully knitted with a special 3-layer structure to enhance heat retention. It boasts the best heat retention because it prevents warm air warmed by body temperature from escaping and shuts out cold air from the outside.

It releases unpleasant stickiness caused by sweat and moisture, and does not leave moisture on the skin side. Because body temperature is not taken away, the part that touches the skin is always dry and does not easily get chilled 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 it 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 men's tights are front-opening types. * The waist elastic itself is sewn on, and the elastic cannot be removed by itself. * Uses antibacterial and deodorizing material Cutery (composite fiber) Remarks: Made in Japan Manufacturer: Kensen Co., Ltd. * The products worn by the mountaineering team are slightly different in materials and specifications from the current products.
