This insulated jacket combines OCTA® dynamic thermal technology with a Pertex Quantum ultra-lightweight, high-density nylon shell to deliver effective warmth without bulk. The OCTA® fiber's unique eight-pointed hollow cross-section creates multiple static air layers, balancing thermal efficiency with breathability and moisture management. Zoned construction places high-loft fleece at the core for warmth retention while incorporating mesh ventilation panels underarm to manage heat and sweat during active use. A stand collar, hem drawcord, and reflective detailing round out a clean, functional design suited to urban commuting and everyday outdoor wear.
