Peter Millar Perth Performance Quarter-Zip in Black

The Perth built Peter Millar's reputation for performance sportswear that never looks the part: a four-way stretch knit that handles moisture-wicking and easy care, finished with a mock collar and banded cuffs and hem for the clean look of a real sweater.

Black is the most formal read on the Perth, at home layered under a jacket for the office or worn alone over a collared shirt for an evening out, while still offering the same performance as it does over a polo on the course.

It's a piece built for the temperature range a dress shirt alone doesn't cover and a full jacket overdoes, which is exactly why it's stayed one of the brand's signature layers.
