Pima Cotton

Pima cotton is an extra-long-staple (ELS) variety with fiber lengths typically running 1.4 to 1.5 inches, versus roughly 1.0 to 1.125 inches for the standard upland cotton used in most tee blanks. That extra length lets mills spin it into much finer, stronger yarn, often 40s to 80s singles, without the fiber breaking; it's traditionally grown in the American Southwest, Peru, and parts of Australia.

Premium private-label lines lean on Pima cotton for the noticeably silkier hand you feel on a $30-plus tee versus a $10 blank, since the longer staple resists pilling and takes on a slight natural sheen most upland cotton can't match. Run your thumb across a genuine Pima tee next to a Gildan 64000 and the difference is immediate — it's not marketing, it's fiber length.

Reserve Pima cotton for retail-facing lines and premium private label where the price point already supports an $8-12+ blank cost; it's wasted on anything getting screen printed for a one-day event. Because true Pima costs more to grow and process, watch for "Pima blend" language on cheaper tags, which often means a small percentage of Pima fiber cut with standard upland cotton to license the name.

Pima and Egyptian cotton aren't the same thing, though tags use them almost interchangeably. Both are extra-long-staple varieties grown in different regions, and neither name is a regulated certification the way "organic" is, so a tag claiming either deserves a look at the actual fiber percentage before you pay the upcharge.
