- Design: SMFK has newly designed the X Extreme Sports Thermal Series for autumn and winter in 2024. It is a minimalist integrated body-shaping flared trousers. The ultra-high-waisted double-layer method can tighten the waist and abdomen while keeping out the cold during outdoor sports. It can be used with thermal body shaping. Jackets are used in combination. The 3M reflective X extreme sports series logo is printed on the outside of the leg.
