These 6 oz. SUPIMA® cotton t-shirts are the world's finest wholesale blank tee, period. Made of ELS (Extra Long Staple) American Grown SUPIMA® Cotton grown in California under strict, quality-controlled guidelines, the hand and feel of this shirt are extraordinary. Additionally, all of our sustainable bulk t-shirts are Oeko-Tex 100 certified, which means no toxic dyes, chemical fertilizers, pesticides, or formaldehyde were used in the production of this product. Sadly, over 80% of the dyes used today in the apparel industry contain toxins, so credible certifications like these are essential. The smooth, soft feel is what we are famous for.
