Satin polyester takes sublimation dye more vividly than standard poly-cotton blends, which is why fight shorts almost always use this fabric when a brand wants a bold, high-contrast design rather than a muted print.
Fight teams and gyms ordering matching competition or training shorts under their own branding are the core buyers, with the split-side kick panel specifically requested by athletes who train high kicks.
Wash in cold water and hang dry to preserve both the elastic waistband's stretch and the vibrancy of the sublimated print over the shorts' training life.
