It's a tee. It's knit like a sweater. It works perfectly. The Driftknit Sweater Tee is made from a lightweight 100% cotton fine gauge knit with an all-over seed stitch — subtle texture, real cotton handfeel. True-to-size with inset sleeves, self-finished openings, and a self-finished hem for a relaxed but intentional silhouette. The kind of piece that looks like you put in more effort than you did.
