Design: SMFK's RAGE handmade workwear series mainly focuses on "visible time" as the design direction, using hand-dying and fading techniques on various iconic workwear fabrics. The low-saturation earth tones and SMFK's classic black and white tones give the entire product a seamless blending and mottled classic texture.

The sports cargo pants developed by SMFK in 2025 are an iconic style that combines denim fabric/sports pants shape/workwear features. They use SMFK textured workwear fabric and the drip dyeing process of hand-dyed garments. They are partially dyed multiple times, one color level at a time, to eventually form a gradient effect. After light frying and fading, the surface of the workwear fabric is slightly sanded to create a cotton matte retro feel.
