Ring-Spun vs Open-End

Ring-spun yarn is spun by continuously twisting and thinning the fibers, producing a smoother, stronger, softer thread; open-end (rotor) spinning is faster and cheaper but yields a coarser, weaker yarn. A ring-spun tee generally feels better and lasts longer for the money, which is why quality basics advertise it and value blanks quietly use open-end. "100% cotton" tells you the fiber; ring-spun vs open-end tells you what was done with it — and it is a common, honest dividing line between a $12 blank and a $30 staple.
