Peter Millar Perth Performance Quarter-Zip in Cottage Blue

Cottage Blue gives the Perth quarter-zip its lightest, most warm-weather read, built on the same four-way stretch, moisture-wicking knit and mock collar construction that's made the Perth one of Peter Millar's signature layering pieces.

It's the version worth reaching for once a heavier grey or navy starts to feel like too much: over a polo for an early tee time before the day warms up, or alone on a cool evening without the weight of a true sweater.

The banded cuffs and hem keep the silhouette clean regardless of season, so this stays a layer that works well past the stretch of the calendar it was designed for.
