3sixteen’s Heavyweight T-Shirts start with a combed, cotton jersey that’s custom knit in Canada, before being cut and sewn in the same San Francisco factory where their iconic jeans are made. The triple-needle coverstitched “Never Sag” collar makes sure it keeps its shape wear after wear, while a special mill-laundering process cuts shrinkage to a minimum. With a tee this well-made, we’re glad they come in a 2-pack.
