Dubbed NSFW (or "not safe for work"), High Sport's compact knit viscose offering has all of the function of the original cotton/Lycra blend, but with an ultra-luxe sheen and feel — if the cotton/lycra blend is day-to-night, this naughtier new fabric is night-to-day. This sleeveless tank features a boxy, relaxed fit that glides sleekly over your high points.
