HARDKORE Supima T-Shirt

HARDKORE Supima Cotton T-Shirts

Made with 100% Certified Supima Cotton grown exclusively in the USA.  Black shirt with HARDKORE logo in gray featured on front chest, back is blank. 

These essential t-shirts are the softest, best fitting shirts we’ve ever worn. The secret? Special and rare long-staple Supima cotton from California’s San Joaquin Valley, which is knit with a new advanced technique called “Baby Jersey” that creates a luxurious and airy fabric.

Supima cotton is a superior, premium type of cotton grown exclusively in the United States (California, Texas, Arizona and New Mexico). It represents less than 1% of cotton grown in the world.  What makes Supima unique to other cottons is the extra-long staple fiber that gives the cotton its premium properties: Greater Strength, Softness and Color retention.
