Terms used on this page

Singles (Yarn Count)
Singles is the yarn-count system where a higher number, like 30/1, means finer, thinner yarn, and a lower number, like 18/1, means thicker, coarser yarn.
Preshrunk
Preshrunk means a garment was run through a shrink-control process at the mill, so most of the size change a first wash would cause happened before it shipped.
Tear-Away Label
A tear-away label is a neck or side-seam tag stitched along a single perforated line so it pulls out cleanly by hand for private labeling.
