The Serifos is a ribbed cotton jumper cut with a half-zip stand collar, built for layering into the colder months. A silver-tone zip pull sits above a fine rib knit that runs vertically down the body and sleeves. Wear it under a wool overcoat on the commute, or alone over a white tee on a walk along the coast on a mild autumn afternoon.

  • Soft Ribbed Hand-Feel: The vertical rib knit sits close without clinging, giving the jumper structure without stiffness against the skin.
  • Half-Zip Stand Collar: A silver-tone zip rises to a stand collar that blocks wind at the neck without the bulk of a full turtleneck.
  • Layer Ready: Wear it zipped to the top over a white tee with dark denim for the weekend, or half-open under a wool overcoat for the commute.
  • Relaxed Through the Body: This jumper is cut with a dropped shoulder and room through the chest; if you sit between two sizes on the Altheny size guide, choose the smaller for a closer layering fit.
  • 100% Cotton: A breathable cotton knit that holds its rib structure and softens with every wash; machine wash cool and lay flat to dry.
