The Seba Works Base Tee is made from a carded open-end six-ounce jersey. The fabric is milled in South Carolina, then knit, cut, sewn, and finished in Los Angeles.

Before cutting, the jersey is pre-shrunk and garment-washed, then treated with an enzyme wash and a reactive dye. A final softening step breaks the fibers down in a way that reflects years of wear, giving the fabric a dry surface with a balanced mix of structure and drape. It carries the feel of a well-worn vintage tee while still holding its color.

The fit is clean and relaxed. The sleeves are cut a little shorter to show more of the arm. The body sits a few inches below the waist, not cropped and not long. The chest has ease without feeling boxy, and the collar has a wider opening with a slightly lower neck drop.
