50% wool. 50% cotton. Rib knit. Crew neck. Sleeveless.Sweater vests are back in a major way. This warm weather season, we’re opting to wear ours with nothing underneath for a look that is equal parts playful and risky. The Rib Knit Vest from Jil Sander is produced in a plush wool and cotton blend that is considerably soft to the touch. The vibrant orange colorway allows it to be the focal point of your outfit, as you can pair it with shorts or pants and your favorite sandals.
