The Corton features a 2-in-1 modular design for ultimate versatility. The body of this convertible style features a water-resistant nylon exterior, tech stretch fleece side seams for mobility, and Primaloft® Gold Insulation for lightweight warmth. As a jacket with the sleeves on, the Corton has reflective arm stripes for visibility at night. Or zip the sleeves off on-the-go and easily store them in the Corton’s clever hidden back pocket. One style, two ways to wear it.
