Supima Cotton Guide: Fibre, Knits and Care
Learn how ROKKX uses extra-long staple Supima cotton across smooth jersey T-shirts, structured pique polos and refined drop-needle knits.
Questions, answered
What is Supima cotton?
Supima is a trademark for extra-long staple cotton grown in the United States. ROKKX uses it in selected T-shirts and polos where a smooth yarn surface, soft hand-feel, and refined colour are important.
How is Supima different from regular cotton?
The main difference is fibre length. Longer fibres can be spun into a finer, more cohesive yarn with fewer exposed ends. The final garment still depends on yarn count, knit density, finishing, construction, and care.
Is every Supima garment the same?
No. Supima describes the cotton fibre, while the knit changes the garment. ROKKX uses smooth single jersey for crews, structured pique for classic polos, and drop-needle knitting for vertical texture.
How should a Supima cotton garment be cared for?
Always follow the garment care label. A gentle cold wash with similar colours and avoiding excess heat generally helps preserve the fabric surface, colour, and fit.
