Relaxed yet refined, the Sienna Sweater Tank from Nation is an elevated take on a summer essential. Made from soft, breathable 100% cotton, this lightweight knit features a bra-friendly U-neckline and a silhouette that’s slightly easy through the body—never oversized. Whether worn on its own or paired with the coordinating Sunna Cardigan, it’s the effortless piece you'll reach for all season long.
